hi,

with unstable as of April 21st, I am getting fairly bad networking performance in my domUs, e.g 125Mbits/s TCP with iPerf over a gigabit link, where dom0 gets around 700Mbits/s.


Hi Jacob,

What were you getting on domU earlier to April 21st? You seemed
to be implying 4/21 build changed something? Was it better before?

Hi,

I am not sure, as before I did not test against a vanilla Xen, but I think the problem was also present in the ~1 month old unstable I was using before.

Jacob
