General questions: Is it possible to improve the server's network performance by adding a second GBit ethernet card? I think a PCI card is bound by the PCI bus performance. Would a second card, if PCI, even enhance performance noticeably? If I upgrade to PCIe, or use a mainboard with onboard GBit ethernet, would that change anything?
A correctly designed mainboard connects the onboard nic directly to the chipset, so you would get better performance with a mainboard that supports 2 GBit nics onboard compared to 2 PCI nics.

Agree with sandy on this, but you need to chose your motherboard carefully, many hang pci bus off the same chipset port (saves chips &$$$) Dumb ? but if their using files this big what about using IPV6 internally as it's designed for large file throughput. You have checked your Switch out? It is a 100base full-duplex and is set that way at the switch AND their cards. Be aware many 100/10 switches can't handle large packet loads at 100 / full duplex and internal bus buffers are small. I've even known them to switch back to half-duplex midstream and then back to full at the end. The same is with the cards, chase drivers that DON'T have 10base config code in. my 2 bits scsijon
