The machines were tested with 2 NICs on the same subnet. The trick NT does is bind each NIC's IRQ to a specific processor. Thus the processing of traffic is more efficient. In the Unix world, putting 2 nics on the same subnet is not exactly kosher and in any event, the Linux kernel doesn't pull the same tricks. Equip both machines with just a SINGLE ethernet card and the results may have been rather different. ===== Need a secure, robust, open-source, multi-platform (9 architectures) OS? Try OpenBSD. The others simply can't compete.
