Ahh that makes sense I guess.

Ok, time to see if JeremyZ will fix some of the Super-Smack compile 
problems on FreeBSD.
About a month ago he said a 1.3 would be coming out very soon.

I'll start posting benchmarks from Super-Smack over the network.

Super-smack is here btw:

If you download it, first thing to do is in client.cc change __FreeBSD to 
__FreeBSD__ to avoid the
ERESTART compile failure.

Regardless, I still think my inital MyBench results were an indication of 
significant performance loss
Vs. (Mandrake) Linux no? Even if it is related to the NIC driver, it should 
be a cause for concern since
the test systems and method was exactly the same.
