Yes, that seems to have made all the difference in the world: % ssh gateway cat /dev/zero | dd of=/dev/null load: 0.08 cmd: ssh 68698 [runnable] 1.20u 0.25s 11% 3020k 94384+0 records in 94384+0 records out 48324608 bytes transferred in 5.314707 secs (9092619 bytes/sec) load: 0.08 cmd: ssh 68698 [runnable] 1.81u 0.33s 15% 3020k 147664+0 records in 147664+0 records out 75603968 bytes transferred in 7.652768 secs (9879297 bytes/sec) So I'm thinking TSO wasn't an option in the older 7-stable I was running and now it is, but the support for it is broken. Your comment about DHCP, would that affect dhcpd or dhclient? This is my "server" machine so I don't run dhclient on it. I hardcode the IP connecting to the DSL modem. I'm currently hardcoding all the other machines also so I should be okay. > 3) Can you disable the firewall (disable ipfw entirely) and see if the > problem continues? Well the firewall is primarily for NAT and port forwarding. There's nothing special about it. It looks like the TSO disabling fixed my problems. Thank you for the suggestion! -- Rick C.
