tcp problem with freebsd 7.1?

[Sam Wun]

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
