Also, the Debian package will pull in OpenJDK by default, but there is
nothing to stop you from using the Sun JVM (which I assume is what's in
use on the other machines). It is even
Will do, thanks for the advice. :)

Do 100k ops first before benchmarking.
Benchmark with multiple threads.
And use a known benchmark first like py_stress.

What's interesting for my case is that I put a timer around the thrift method

Every iteration of that call against debian (any hardware, same network or in

so I can compare the two for speed, because either I’ve got crap for

Thanks for the reply Jonathan!
I started with multi threaded tests, but when my performance was so much
slower than my buddy's I switched to one to try to isolate and identify the
differences. I got tunnel vision and kept on with the one thread tests.
I'll modify the tests and try again.
Thanks
A single-threaded test is meaningless. You need a multithreaded (or
multiprocess) benchmark like the one in contrib/py_stress.
