High Availability Performance Testing
Load testing is an important part of ensuring that the CAS server deployment is ready for prime time production use. This page outlines a number of strategies and tools you may use to run performance tests on your deployment and observe results.
Locust is an easy-to-use, distributed, user load testing tool. It is intended for load-testing web sites (or other systems) and figuring out how many concurrent users a system can handle. See this guide for more info.
Apache JMeter is a great performance testing tool that is used heavily within the Java community. See this guide for more info.
