This contains JUnit tests to help with performance measurement and tuning.

All these tests should pass on a warmed-up production machine, but in any case the numbers generated should be useful.

Beware of the micro-benchmark nature of these tests, especially the smaller ones, that may not, for example, a HotSpot VM to profile and compile code in time for the benchmark to be representative, so it may be a good idea to run tests repeatedly until performance settles down.
