Not to sound like an ass :D
but can you back that up?
I've read quite the opposite. Granted there has been some glitches in some of the serverworks chipsets, but nothing that would hinder its performance signifcantly. If anything I have seen numerous performance benchmarks comparing the high end (intel) p3 x86 motherboards like the 820 and GX and it can't come close to what the low end serverworks chipsets could produce for bandwidth.

I am curious to see what type of problems you had because prior to the new xeon chipsets that came out serverworks was about the best thing for the p3 server line, which handed out the capabilites of being able to keep up with gigabit and fibre channel HBA. The above link was given to test throughput capabilities for the HBA adapters. It really tests the motherboards PCI bus capabilities.
As far as GB Ethernet sure you can fill up the pipe with multiple file transfers, or mulitplie clients hitting hard off an interface, but my goal was to fill the pipe with a single file transfer so that you can achieve maximum throughput when you need it. Also I think Jumbo frames are going to be more important once 10G rolls out. I think there will very little benfit of 10G unless they implement jumbo frames. I guess I have done a fair amount of testing and tweaking to try to achieve this without jumbo frames and the results have been less than great. We will how much of a difference jumbo frames make in the weeks to come.
