Hrmm... Have thought about the cables - may be worth a shot as the cabinet is so tight, but it is a long shot...
Aah... A Nvidia "softnic" is on-board both of the machines, and a PCI Realtek. On Debian the Nvidia is eth0 and Realtek eth1 and vice versa on the Ubuntu. Not sure on any control utilities - been a while since I've examined nic drivers (or any other drivers for that matter). I'll check it out. (Refernces welcome :) Thanks heaps for all your help!

So you've got an Nvidia "softnic" (rather like a softmodem, so kind of icky if you're looking for performance) and a Realtek, which are not widely known for their performance. I'm not sure that explains the full extent of your performance problems, but it's a start. Are there any control utilities or module parameters for forcedeth? Perhaps you could switch it between performance modes (to favour CPU or throughput, pick your poison). Long shot: Make sure you have a good cable. - Jeff -- linux.conf.au 2007: Sydney, Australia http://lca2007.linux.org.au/ "Suddenly there was a terrible roar all around us, and the sky was full of what looked like huge bats." - Raoul Duke, Fear and Loathing in Las Vegas -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
