Turning hyperthreading off hasn't helped. Ping response times are still slowly increasing.
I just put up another set of graphs that might be the most interesting yet.
http://depot.mtholyoke.edu:8080/tmp/depot-depot/2002-02-12_10.30/
They show depot, a very lightly used machine, monitoring itself, running e1000, then being rebooted to use a new kernel with ACPI support, then having the e1000 module swapped out for the bcm7500 module (switch back to built in NIC). Reboot brought response times down to almost zero. Switching module/NIC had no effect at all.
Does anyone have any ideas of things they'd like me to try? My imagination is running dry. I have non-production 2650's and beige boxes I can try stuff on.
