To quote from the LINT file (this is 3.3-STABLE): "# Network interfaces: `cx', `ed', `el', `ep', `ie', `is', `le', `lnc' [snip] # ep: 3Com 3C509 (buggy)" This driver is slooooow, it is a known problem. I suggest sticking with the PCI nic for now. In general there is a difference between ISA and PCI but not this dramatic of course and it varies from location to location. I use a non-brand NE2000 PCI card as ed1 and I am content with it this far although we have a high-speed LAN Internet connection here so it should show if there were problems. Cheers!
