Simple performance testing using ab

When testing performance the main issue is the difference between before/after a change. There is no real success/failure, mainly a reasonable response time, and response time change in percentage.

When testing performance, it is also important not to just execute one request, but to make some kind of load on the server.

Apache Benchmark is a quick and simple testing tool that can be useful for such a quick test.

Notes: If you need to test an authenticated user you need to follow some steps (TBD) to make use of an existing session. If you test as an anonymous user, just make sure the caching for anonymous is disabled.
