Time to Interact (TTI)	50 ms	0-7.3 ms	Above 7.3 ms
Load Time	3 seconds	Average 15 seconds	Above 15 seconds

By keeping an eye on these metrics, developers can spot and fix slow spots. This makes websites work better and gives users a smooth experience⁷⁸.

Server-side Performance Testing Metrics

Client-side performance metrics focus on how users feel when they use a system. But, server-side metrics are key to seeing how the system’s back-end handles its workload. These metrics show how well the server can handle tasks, stay reliable, and work efficiently. Let’s look at some important server-side performance testing metrics to watch.

Requests per Second (RPS)

The Requests per Second (RPS) shows how many requests a system, like a search engine, can handle in a second. It’s a key way to see if a server can keep up with traffic⁹. A high RPS means the server can handle lots of requests well. A low RPS might mean it’s struggling or needs more power.

Uptime

Uptime tells us how often a server or app is available and reliable⁹. It’s vital for a good user experience. High uptime means the server is always ready and quick. Low uptime can mean problems with stability or maintenance.

Error Rates

Error Rates show how often requests fail compared to all requests⁹. High error rates can mean the system is having trouble or failing. Watching error rates helps find and fix problems for a smoother user experience.

Thread Counts

Thread Counts show how many requests the server can handle at once⁹. This helps spot issues with handling many requests at once or running out of resources. Looking at thread counts can show how well the server manages many requests and where it can get better.

Metric	Description	Importance
Requests per Second (RPS)	The number of requests an information retrieval system handles in one second.	Crucial for measuring the server’s capacity and handling capabilities.
Uptime	The measure of the overall availability and reliability of the server or application.	Essential for ensuring a consistent user experience.
Error Rates	The percentage of requests resulting in errors compared to the total number of requests.	High error rates can indicate performance issues or system failures.
Thread Counts	The number of concurrent requests the server receives at a particular time.	Helps identify potential concurrency issues or resource bottlenecks.

By keeping an eye on these server-side performance testing metrics, you can understand how well your application’s infrastructure is doing. This helps you make smart choices and improve the user experience.

Start Testing Early

Good quality assurance¹⁰ starts early in the software development lifecycle. Early performance testing can spot and fix big problems before they cost too much¹⁰. Waiting too long to test can lead to big problems, like what happened with the Twitter Android app¹⁰.

By shifting left and adding performance tests to the Continuous Integration/Continuous Deployment (CI/CD) pipeline, teams can find issues fast and fix them well¹¹. It’s important to set clear Key Performance Indicators (KPIs) for a good testing plan¹¹.

1. Use real data and scenarios in tests to make them more reliable¹¹.
2. Watch how the system acts during tests to find where it slows down or doesn’t work well¹¹.
3. Get developers, testers, DevOps, and product managers working together to speed up getting things to market¹¹.

Metric	Description
Response Time	The time it takes for a user request to be processed and a response to be returned.
Throughput	The number of user requests that can be processed within a specific time frame.
Error Rate	The percentage of user requests that result in an error or failure.

Every test cycle gives important data for making code and tests better¹¹. Starting performance testing early helps find and fix problems before they get too expensive¹⁰.

“Load testing helps ensure that your application is ready for production to avoid costly downtime¹⁰. Load testing is crucial for identifying where and when your application breaks under pressure¹⁰.”

Embracing Early Performance Testing

Adding early performance testing to the development process has many benefits¹⁰¹¹. This approach helps find and fix performance issues early, stopping them from getting worse¹⁰¹¹.

Performance testing techniques

Ensuring software applications run smoothly is key. Performance testing is vital for this. It checks how well software works under different conditions¹².

Load testing checks how an app handles normal or high user loads. Stress testing tests how far an app can go before it breaks, showing its weak spots¹².

Endurance testing looks at how an app stays stable over time, like when used a lot. Soak testing is similar but focuses on constant use without slowing down¹².

Spiking testing quickly adds more users to see how an app reacts to sudden demand. It checks how well the app handles more users at once¹².

These tests make sure the software can handle various user loads, resource issues, and long use. They ensure a smooth experience and successful launch¹².

Performance Testing Technique	Purpose
Load Testing	Evaluates application behavior and stability under expected or peak user loads
Stress Testing	Pushes the application beyond its limits to determine its breaking point and identify potential weaknesses
Endurance/Soak Testing	Assesses the application’s performance and stability over an extended period, simulating prolonged usage scenarios
Spike Testing	Rapidly increases the user load to observe the application’s response and behavior under sudden spikes in demand

Choosing the right performance test depends on the app’s needs. These tests help teams check the software’s performance in various situations. This ensures a smooth user experience¹².

“Continuous optimization through performance testing is vital for the success and productivity of modern applications.”¹²

Using a detailed performance testing plan helps find and fix problems early. This leads to stronger and more efficient software¹²¹³.

Pick Your Metrics

Choosing the right performance metrics is key for a good testing strategy. Metrics like load time, response time, and time to first byte are important. But, don’t forget about stability metrics like maximum requests per second, peak response time, throughput, and bandwidth¹⁴. Pick metrics that match your project’s goals and what users need¹⁴.

Looking at just average values isn’t enough when checking performance¹⁴. You need to look at standard deviation and percentile values too. These give a full picture of how the system works and what users experience¹⁴. Using percentiles, like the 90th percentile (p90), helps set clear service-level agreements (SLAs) and check if something meets standards¹⁴.

1. Load testing shows how an application does under a lot of user traffic. It helps understand its limits¹⁵.
2. Stress testing checks if a system can handle too much work and stay stable¹⁵.
3. Spike testing sees how a system does with a sudden increase in data or tasks. It checks stability under unexpected loads¹⁵.
4. Endurance testing looks at how long a system can run without errors. It shows reliability over time¹⁵.
5. Scalability testing makes sure a system can handle more users or tasks without breaking down¹⁵.
6. Volume testing checks how a system handles a lot of data and responds quickly under heavy traffic¹⁵.

Metric	Description
Response Time	Shows how fast the system responds to tasks, helping spot performance issues15.
Load Time	Checks how fast an application or website loads, important for keeping users happy15.
Throughput	Looks at how many tasks a system can do in a set time, showing its speed15.
Concurrent Users	Sees how many users or devices can use the system at once, testing its performance under heavy use15.
Requests per Second (RPS)	Measures how well a system handles tasks, showing its workload management and reliability15.
Error Rate	Finds out how often the system makes mistakes or doesn’t work right, pointing out areas for improvement15.
Transactions Passed/Failed	Keeps track of tasks completed without errors, checking efficiency and system performance15.
Bandwidth	Measures how much data is transferred in a time, affecting file downloads and system speed15.

Picking the right performance metrics and understanding them well helps build a strong testing strategy. This strategy should match your project’s goals and give users a smooth experience¹⁴. Regularly checking and adjusting these metrics keeps your system running well and meeting user needs¹⁴.

“Looking at percentile values is key for setting standards and understanding system behavior. Be careful not to just focus on averages as they can be misleading and hide important details.”¹⁴

Build a Testing Software Suite

Building a good testing suite means having various tools for load testing, API testing, and automation¹⁶. Using these tools with your current QA setup makes testing smoother and aligns better with other tasks¹⁶. It’s smart to look at what AI testing tools can do to improve your testing plans¹⁶.

When making a testing suite, think about what your app or project needs. Key areas to focus on are:

• Load Testing: Tools like JMeter and Taurus help simulate traffic and find performance issues¹⁷.
• API Testing: Tools like Postman and SoapUI test your API’s function and speed¹⁶.
• Test Automation: Frameworks like Selenium WebDriver, Appium, and Cypress automate tests, making them faster and more consistent¹⁶.

Adding these tools to your QA workflow makes testing smoother and keeps performance in mind from start to finish¹⁶. Looking into AI testing tools can also help make your testing better and find areas to get better¹⁶.

Creating a strong testing suite is a continuous task that needs constant improvement¹⁶. By keeping up with new tools and best practices, you make sure your testing is giving you the right insights and results for your project’s success¹⁶.

Organize Your Tests

Organizing performance tests can be tough, especially with many tools¹⁸. A solid routine, like naming tests and structuring them, keeps things in order¹⁸. Treat performance tests like any other test suite to start simple and improve over time¹⁸.

Establishing a Good Routine

Creating a good routine means focusing on finding and fixing performance issues¹⁸. Making test setups modular helps with reuse and teamwork¹⁸. Using environment variables for different settings makes testing smoother¹⁸.

Using Test Management Solutions

¹⁹ Test management tools with workflow features make performance testing easier and help new members join¹⁹. Regular meetings and workflow tools keep things structured¹⁹. Aligning performance testing with other company tools boosts efficiency¹⁹.

In summary, to organize performance tests, use naming conventions, structure tests, and dependencies¹⁸¹⁹. Also, use test management tools with workflow features¹⁸¹⁹. This keeps things in order, improves testing, and helps new members join¹⁸¹⁹.

Ask Your Users

Performance metrics are key, but don’t forget about the user experience²⁰. Heatmaps and session recordings show how users really feel about performance issues²⁰. This info helps focus on what needs fixing and makes sure testing meets user needs²⁰.

User feedback is vital for testing performance. Talking to your users helps you understand their problems and what they expect²¹. This shapes which metrics and scenarios to test, making sure you tackle real user challenges.

To get user feedback, try these methods:

• Use user surveys to get direct thoughts on how your app or site performs.
• Look at reviews and comments on app stores and social media for common complaints about performance.
• Check user support tickets for frequent performance issues.
• Join in with your user community through forums or testing sessions to learn more about their needs.

Adding user insights to your testing makes sure you’re focusing on what users really want²⁰. This approach leads to a better experience for your users, which means more people will use and enjoy your product or service.

“Understanding the user experience is just as important as measuring raw performance metrics. By listening to our users, we can unlock valuable insights to guide our optimization efforts.”

Set Clear Performance Testing Objectives

Setting clear goals for performance testing is key. It guides the testing and makes sure the app meets the needed standards²². Important things to think about include response time, how much resources are used, how much work it can do, and how much work it can handle²². With clear goals, you can check how well the app is doing and find areas to get better.

Response Time

Response time is key. It’s how fast the app answers user requests²². Having clear goals for response time helps with testing and makes sure users have a smooth experience²².

Resource Utilization

Watching how much CPU, memory, and database are used helps find bottlenecks and makes sure the app uses resources well²². Setting goals for resource use helps make the app better and ready for the workload²².

Throughput

Throughput shows how many tasks the app can do in a set time²². Having clear goals for throughput checks if the app can handle the expected load and finds areas to improve²².

Workload

Knowing what workload to expect lets you set realistic testing goals and check if the system can handle it²². This helps plan tests and make sure the app can meet user needs²².

Aligning testing goals with the project’s aims and what stakeholders want makes sure the app performs well and meets everyone’s expectations²². Keeping an eye on these goals during development helps make the app better and successful in the long run²².

Align with Project Goals

Successful performance testing is more than just running tests and looking at results. It means making sure the testing matches the project’s main goals²³. The goal is to align the testing with the project’s aims, like making a reliable app, handling lots of users, or checking new features work right²³. This way, testing focuses on what’s important and gives useful insights for better results²³.

First, understand the project’s goals and what it needs²⁴. A detailed test plan is key, listing what to test, how, and why²⁴. This plan must match the project’s big picture and tackle the main issues and priorities²⁴.

Think about the project’s limits, like budget, time, and resources²⁴. Adjusting the testing to fit these limits makes it more effective²³. This might mean picking which tests to do first, using automation, or focusing on the most critical parts²⁵.

The aim is to make sure testing helps the project succeed, not just adds extra work²³. By keeping the project’s goals in mind and shaping the testing strategy around them, apps can be made more reliable, scalable, and functional²³.

Performance Testing Objectives	Mapping to Project Goals
Ensure application reliability under high loads	Build a reliable application
Verify application scalability to support future growth	Ensure scalability under heavy loads
Validate the functionality of new features	Verify the functionality of new features

“Aligning performance testing with project goals is the key to delivering meaningful insights and driving real improvements.”

Stakeholder Analysis

Starting with a detailed stakeholder analysis is key to making a good performance testing plan²⁶. It means understanding what the project needs, working with different teams, and making sure the testing goals match what stakeholders want²⁶.

Stakeholder analysis is vital for finding and figuring out how important, influential, and interested different people are in a project or decision²⁶. It helps make a full list of those affected by the project and sorts them by how much they care and can influence things²⁶.

Doing regular stakeholder analysis helps spot the most important people with the most interest in the project²⁶. Knowing what motivates stakeholders is a big part of this analysis²⁶. Using the right tools to get insights from stakeholder analysis is key for making good decisions and handling conflicts²⁶.

Getting stakeholders involved in decisions makes things more open and builds trust²⁶. Projects that think about what stakeholders want are more likely to do well because they tackle problems early²⁶. Listening to what stakeholders say can make an organization look better, building trust and credibility²⁶.

Stakeholder analysis is an ongoing task that needs to be done often to keep up with changes²⁶. Doing it early in a project helps plan how to engage stakeholders²⁶. It should be done at each stage of the project or every six months to make sure stakeholders’ needs and hopes are met²⁶.

Stakeholder analysis is done at global, national, and local levels in health policy studies²⁷. Studies show that stakeholder analyses often lack details on how power, interest, and position work together²⁷. A new framework for stakeholder analysis includes four key traits: knowledge, interest, power, and position²⁷.

Stakeholder power is seen as potential power based on resources and position, showing how power is really used for or against a policy²⁷. Power affects policy implementation in many ways, touching every step of the process²⁷. Challenges in stakeholder analysis include capturing changing stakeholder views and separating personal and role-based opinions²⁷.

Considering both top-down and bottom-up approaches is important when looking at stakeholders at different levels²⁷. Stakeholder analysis can be done looking back or forward through the policy cycle for health policy research²⁷. There are different kinds of power in policy making, like ‘power over,’ ‘power with,’ ‘power to,’ and ‘power within.’²⁷

Stakeholder analysis is about finding and evaluating people, groups, or organizations that care about a project’s outcome²⁸. It’s crucial for a project to succeed²⁸. A stakeholder analysis can help get more support and resources, make the project more visible, avoid costly delays, communicate well, and share the right information²⁸.

There are two main types of project stakeholders: those inside the project and those outside²⁸. Those with a lot of power and interest need close attention²⁸. Those with a lot of power but less interest should be kept happy and informed²⁸. Those with less power but a lot of interest should be kept in the loop and involved²⁸. And those with little power and interest should still be watched and informed²⁸.

Identifying and managing project stakeholders is key to a project’s success²⁸. There are four main groups of stakeholders based on how much influence and interest they have: high influence and high interest, high influence and low interest, low influence and high interest, low influence and low interest²⁸.

“Stakeholder analysis is an essential component of effective performance testing, as it ensures that the testing strategy aligns with the needs and expectations of all relevant stakeholders.”

System Architecture Assessment

Looking at the system architecture, like the load generator, application under test, and monitoring and analysis tools, is key for a good testing setup²⁹. It spots problems or bottlenecks early, before testing starts²⁹.

Checking the system architecture means looking at all parts of the testing setup. This means checking the load generator’s strength, making sure the app is set up right, and checking if the tools for monitoring are enough for the job³⁰.

By really looking at the system architecture, teams can find things that might slow things down, like hardware issues or network problems. This info helps make the testing better, giving more reliable data³⁰.

Component	Considerations
Load Generator	Can it make the needed load? Can it act like real users? Works well with tools for monitoring and analysis
Application Under Test	Is it set up right? Works with testing tools Has all needed resources like databases, APIs
Monitoring and Analysis Tools	Can it track important performance metrics? Works with the testing setup Can give clear, useful insights

By looking closely at the system architecture and fixing problems, teams make sure their testing is top-notch. This leads to better decisions about how well apps and systems work³⁰.

Test Data Strategy

Creating a strong test data strategy is key for performance testing. It should be realistic and come from real-life situations. This helps avoid overloading the system³¹. Having a clear process for managing test data makes testing smoother³¹.

More companies are using tools for test data virtualization and synthetic data creation to solve their problems³¹. A good test data strategy has three main steps: Understand Your Data, Find and Make the Right Test Data, and Deliver Test Data Effectively³¹.

AI and machine learning can now automatically find important information in big data sets, making test data better understood³¹. There are many ways to manage test data, like subsetting, masking, synthetic generation, and virtualization, depending on what you need³¹. For example, you might need lots of data for performance testing but only certain data for functional testing³¹.

Getting test data to testing environments quickly is important. This can be done through virtualization, self-service access, automation, and integrating with testing tools³¹. But remember, just using virtualization or synthetic data isn’t enough. You need a full test data management strategy³¹.

Choosing the right test data tools is crucial. The wrong tools can hurt your test data efforts³¹. It’s important to know your needs and environment before picking tools³¹. Having the right tools for each step of the test data process is key to a good strategy³¹.

Managing test data well is like building a house. You can’t just use a hammer or screwdriver alone. You need the right tools at each stage for a successful test data management³¹.

Curiosity Software has over 30 years of experience in test data. They can help improve your test data strategy³¹. Their expertise can help you set up a strong and efficient test data management process³¹.

Companies are also using data masking tools for privacy and security³². Synthetic data generation is helpful when you can’t get enough data from production³². A full test data management system that refreshes data for each component and works with many systems is essential³².

Security Measures

Performance testing often deals with a lot of data, which can be risky if not handled right³³. It’s key to use strong security steps like access controls and data protection to keep data safe and follow rules³³.

Security testing is a big part of performance testing. It checks how secure a system or app is³³. It looks at six main security areas: keeping data private, making sure data is not changed, verifying who is accessing, controlling who can do what, making sure data is available, and proving actions were done by someone³³. Important security testing focuses on network, system software, and application security, plus checking who can log in and what they can do³³.

There are many ways to test security, like checking for weaknesses, scanning for security issues, testing how well systems stand up to attacks, and doing risk checks³³. Tools like Nessus, OpenVAS, and Metasploit help with these tests³³. Security testing finds problems, makes systems safer, follows rules, lowers risks, and helps with handling security issues³³. But, it can be hard, take a lot of time, and sometimes find things that aren’t really problems³³.

Recent big cyber attacks, like the one on the Central Bank of Russia and Ukraine’s government sites, show why strong security is vital³⁴. Businesses face threats like SQL Injection, malware, phishing, and more³⁴.

Using new security testing methods, like checking apps for security, testing how apps work, and simulating attacks, can find and fix security issues³⁴. Penetration testing and security checks are key to keeping DevOps safe³⁴.

Bright Security is a top choice for security testing, offering solutions for web, API, and more³⁵. They help find and fix security weaknesses to keep data safe³⁵.

A strong test data strategy is vital for performance testing. Use real-life data wisely to avoid overloading the system. Have a clear process for managing test data to make testing smoother.

What Security Measures are Important for Performance Testing?
