Actually, that reminds me.  Many motherboards with integrated 
network cards are now coming with something called "Checksum 
Offload" switched on.  This supposedly makes throughput better by 
making the CPU do more of the checksumming work instead of the 
NIC, but in practice all it seems to do is to significantly 
increase the number of bad packets and consequently packet 
retries.  So it might pay to check that out.  (I'm not sure if 
it's a driver-level "feature" or if it's something in the 
hardware, and consequently whether it'll affect non-Windows 
servers or not.)
