Optimizing throughput on file transfers through gigabit ethernet adapters and x-over cat6 cable

Both computers running Windows XP Pro, connected via x-over cat 6 ethernet cable. When I transfer large files, the sustained transfer rate peaks at 25% of network bandwidth or approximately 250Mbps and usually hangs around 15-20%.

I've tried turning off QoS, changing the QoS reserved bandwidth to 0%, changing the frame size to 7500 (smallest maximum supported between the two nics), transfer via FTP (which turned out to be a lot worse).

What else can I try?
 
don't expect 1000 Mb/s from gig...I think Jack has a link to realistic expectations. Also, what brand are the cards, what slot are they in?
 
I usually top out between 22-26% and attribute it to my drives than anything else.
At 260Mbps that is 32MB\s sustained. Realistically I dont know how much faster IDE drives are at reading\writing sustained.
