Hey,
Since switching to AMD64/nF4 from an Intel setup, I've noticed higher CPU usage, higher RAT and what looks to be PCI-bus limited sustained transfer (although this shouldnt be the case since I'm running straight off the nF4 SATA ports?!). First pic is my old Intel, second pic is the new nF4.

See how the sustained rate seems to hit a ceiling at about 100MB/s whereas on my Intel setup it tops out higher at about 120MB/s? Smells like PCI bus limitation, but I was under the impression that the nF4 SATA ports were directly connected to the SB (not even PCI-E), so in theory the only limitation is the HTT bandwidth!
Cheers,
Suman
