Open Source Performance Testing Tools List

Test is the best way to validate your application, but how do you know that it’s working as intended? This answer is Performance Testing. It involves automating tests that measure application performance. At the end of the day, performance testing helps improve website/app speed and availability for real users. It is an important part of software testing because its main focus is to monitor high traffic on servers and websites plus its main goal is to determine if your website is showing signs of slow response time and whether it can handle heavy volumes, or not. This post will introduce 10 open source performance testing tools for web applications. Let’s get started:

LoadNinja

Conclusion

Performance testing is an integral part of discovering and resolving bottlenecks and outages in a system. Additionally, understanding performance trends over time can help with capacity planning and anticipating bottlenecks before they happen. Performance testing measures how well an application will perform in the future by stressing it with an overload of simultaneous users. But there are many performance tools that exist and it can be hard to figure out which ones are best suited to your project’s needs.
