Although your email has all the classic hallmarks of a troll, I will
rise to the bait.
You need to post your hardware and software configs for both OSs, along
with your test methodology to get anything other than the email

your kernel conf, make.conf, dmesg, etc. and their Linux counterparts.
In the test methodology, include the names of whatever benchmarking
software, if any, that you used. Don't forget the stats that showed the
claimed perfomance difference. Throw in anything else you think that
one would need to reproduce your tests.

really anti-American. Besides, I have to go, someone's pounding on the
