We have had some issues with NIC drivers in the past.. what Nics are
you running. Specifically some Nics need to have the CRC checks
disabled.
This also sounds like state is not being kept on the IP Filter if you
are running one. Do you have more details?

Hi,
With regarding to the following statement, is there any serious tcp
problem with freebsd 7.1?
"We recently found our new FreeBSD server (located in some foreign
region) has poor network performance. After doing some tcpdump and
iperf testing, we found that out-of-order TCP packets are not inserted
into queue.
This is an 100Mbps line, and TSO is disabled. "
Very appreciate for any suggestion.
Thanks
