"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
