Output how? A single-stream output, or output to multiple (hundreds or

Clients are the thousands HTTP browsers in the Internet. Both servers
contain the same static content size from 2Kbytes to 1Mbyte.
How many simultaneous users is the typical figure?
Is polling enabled? How have you tuned FreeBSD performance?
Have you been able to figure out what's the bottleneck on linux vs on
freebsd? Is it CPU (which process?), interrupts, disk-IO, ...? (top,
vmstat, etc. maybe help in that)
One thing that is different in Linux/FreeBSD is rfc1323/window-scaling
support. I suspect you've already checked it, but I'd verify that
both systems are sending out and receiving similar-looking packets
(for example, similar MTUs, no fragmentation, no ICMP packet too bigs,
...)
