I've also seen this problem, ne2000 clones work like magic in kernel 2.0.x but in 2.2.x and 2.3/2.4 they use about 90% cpu when doing 10Mbit/s traffic on a Celeron 366A. I've seen this with both ISA and PCI based ne2000 clones, the PCI based didn't use more than 70% cpu. I remember that when I ran 2.0.x I could play quake on my old AMD K6 200 when my machine acted as a 10Mbit router (2 ISA ne2000 clones). But when I upgraded to 2.2 I could hardly use 1 of these cards anymore, the machine was completely unusable during high network load. > I observed that those high loads appear when users copy large > amount of data from one another (ftp or win exlporer copy), not from the > server. that's bridging. my ping with the server goes up to 20-50ms and > the box hardly respond to any commands. I had the same problem, it's the ne2000 NIC's that's the problem. /Martin - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.rutgers.edu
