Do the test with netblast ;)
Most perf tools are written badly and for Linux.
In our internal test netblast running on freebsd outperform everything else.
P.S. - /usr/src/tools/tools/netrate/netblast - we have tested little more
expensive card - em/igb and bce.
Now I install 8.2-RC2/i386 and use netblast:

I test network performance and found some strange result -- on the
same hardware Linux more then 10x used CPU resources for interrupt
processing.
FreeBSD system utilise 70% CPU (32% idle, 59% interrupt, 9% sys) and
network card generate 14K-18K interrupt per second.
Linux system utilise 20% CPU (80% idle, 13% system, 3% hiq, 4% siq)
and network card generate 56K interrupt per second.
I used 'netperf -H host -t UDP_STREAM -l 60 -C -c -- -m 8972 -s
128K -S 128K' for generate network traffic.
