Well, I changed the io scheduling on the dom0 to use deadline and got a
30% improvement. I then noticed that the domU was using the noop
scheduler, so for kicks I changed that to be deadline as well. Now I'm
going about 3 times faster than when I had been this morning. At 6MB/s
scap speed over 100Mb ethernet, that's not exactly where I want it, but
it's an awful lot better.
Thanks for this suggestion!
Glad that it helped. We're very aware of the performance and have a few
things in the works for network and general scheduling. It definitely
will continue to improve.

It's an adaptec card, and I've seen it push over 25MB/s before I went

Try changing the I/O elevator to deadline for dom0 and report back on
the thruput. As there is planned tuning work this could change, but
for now it may dramatically help.
