x>On an AMD Athlon64 3200+ (2 GHz) I was able to saturate 2 PCI-Express gigabit cards (but that was with 1500 byte packets). Never tried more although the box has 6 interfaces capable of gigabit, >4 of them attached via PCI-Express. What NIC's are you using? Are they multiport or do you have several pci-express single port cards? Andy Registered Office: J.O. Sims Ltd, Pudding Lane, Pinchbeck, Spalding, Lincs.
