They have continued with 7.2-STABLLE. Reverting to the 7.1-STABLE kernel eliminated the problem. After downloading 7.2-STABLE from cvsup.freebsd.org at about 10:40 AM EST on 5/20/2009, doing a buildworld/buildkernel/installkernel/installworld cycle I still need to execute "net.inet.tcp.tso=1" to elminate throughput problems between my home system (on Comcast) and my office PC (connected via a Time-Warner connection). This also affects connections to other systems; downloading Web pages (ebay.com) speeds up after I change the TSO entry. The box in question runs NAT and has an fxp (Intel Pro100) interface connected to a Comcast cable modem and an em (Intel Pro1000) interface connected to the internal network. There are no network errors in "netstat -i" on either interface. The "if_fxp.c" code appears to be the May 7 version. This is the dmesg entry for the card in question. The system is a dual Xeon Supermicro 1U box, 1GB RAM, single 300GB IDE hard drive. fxp0: port 0xe400-0xe43f mem 0xfebfd000-0xfebfdfff,0xfeb80000-0xfeb9ffff irq 27 at device 7.0 on pci0 miibus0: on fxp0 Mike Squires
