Load testing is very important part of the testing
cycle. It allows you to test your application under stress by increasing the
parallel users of the application. To perform a good load test, you need to
generate more and more traffic, which you can't do only using your development
machine. As a solution, you can use load test rig to generate more traffic to
your application. Load test rig is made up of one test controller machine and
one or more test agent machines. Test controller coordinate the agent machines
and agent machines generate load against the application.
