Hi,

I think such core infrastructure thing like LAN speed/duplex configuration should be fixed, leaving less room for problems coming for autonegotiation stuff. That's pretty much the same reason why one shouldn't use DHCP for servers.

Actually I've seen some performance issues with new HP servers (DL380 and DL580
series) and Cisco 2950 switches. For some reason, nailing both the NIC and the
switch slowed performance. It was the goofiest thing I had ever seen. Setting
both sides to autonegotiate brought the link up to 100/Full, and performance
improved.
