I just brought up a 4.3-RELEASE system and I'm getting very poor Ethernet
performance. I've attached the dmesg file at the end of this message so give
an idea of the system config. Essential, it is a 800MHZ P3 system with 256M
ram, two UDMA 100 IDE drives, a SMC EZNET (SMC1121TX) PCI Ethernet Card, and
a PCI Video card. Pings from machines on the same net take about half a
second. traceroute doesn't show any network loops. netstat doesn't show any
errors. Other systems on the network are getting very reasonable
performance.

Any ideas on what might be going on? Where can I start looking?
Thanks,
Kory
