I'm trying to figure out why it can saturate the gigabit link with 3 transfers going, but not with just one. Thanks for the suggestion, but I already tried this. I tested with both ends having Jumbo Frames on and off, and there doesn't seem to be much speed difference either way.

Besides, I think Jumbo Frames are a bit overrated. I remember messing around with Jumbo Frames a few years back, thinking it would improve network performance.
