Re: expected disk performance? |
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!

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.
