Performance testing is a fantastic tool with unique features which can be customized tests on different test cases, which can determine regression testing, load testing, and speed testing.

Performance Testing makes sure that our servers can handle the predicted number of users and sudden spikes of user loads as we do Load Testing, Stress Testing, and Endurance Testing in advance. After doing Performance Testing of our servers, we ensure that we will not lose our customer's trust and also not lose our reputation in the market if our servers face sudden spikes of requests. With Performance Testing, we also need to understand the elasticity and resiliency of our server's infrastructure.

I think this tool is very usefull in terms of identifying performance leakage for your requirement in a very easy-to-use way. The good thing about this product is that you can customize your test in any way as far as your requirement is concerned.
