Sure, I'll share benchmark test suites, please, see attachment.
There are 2 suites: Bentley's and mine. First suite runs
test on many data inputs with several parameters. In my suite
I run only on random, sorted, equal, stagger, period.
In config file s.bat you should change JDK location.
Note that I run on JDK *7*, build 1.7.0-ea-b84.
It will be very interesting to see results on your machine.
