The ability to run load tests in short or long duration with different CPU cores available for execution. It also provides a GUI interface which can be used by non technical users as well. I haven't come across any issue so far but would love it if support team could extend some more features like - Auto pause once test completes successfully (so we don't need to click 'pause' each time) - Ability to store data from one test session into another so we have same results when running later tests. Please refer few articles online regarding setup requirements and understand them properly prior you jump feet first into this product. We use ApiLoadTest heavily for API Performance Testing. Our customers use our API services and applications where we provide them analytics reports using ApiLoadTest's APIs. In addition, our developers also uses Apiloadtest to check.
