Let's see. Using HW of the same spec, domU <-> domU (same dom0):
- Windows 2003 : 530 Mbps (this is the previous result)
- RHEL 5.2 (PV) : 2.7 Gbps
I don't have a pair of Linux HVM domUs with PV drivers to check.

I'd say there's a lot of room for improvement :)

I'm not sure where you've gotten those numbers from but I'm curious why I don't. I have two companies using Xen on CentOS 5.2 with CentOS 5.2 DomUs and I'm getting the same numbers on both. DomU to Dom0 (or anywhere outside) is as fast as the hardware. DomU to DomU runs about 450-500Mbits/sec. It's consistant so far. If I could get 2.7 Gbps I'd be happy as a clam but I haven't seen it.

Some people, when confronted with a problem, think "I know, I'll use Windows."
Now they have two problems.
