While doing performance tests in this area, I always had a feeling
that OS layer (scheduler that flushes OS buffers) had a role to play here, So I use to reboot m/c between tests,
ofcourse taking performance data in this fashion is tedious. I think it is good to run tests on m/c with configuration
similar
to what Jim Nasby mentioned in his below mail.
