I had similar issues - it looked like the internal network was running at about 100 Mb/s. But this seems to be caused by CPU scheduling, rather than any explicit speed limits.

See these posts I made for more info:

Hi

For my taste VMs in xen are nearly TOO realistic.
I want to tranfer data between two domUs and I get about the same speed when
I
1) transfer over my provider's router (xenbr0 - router - xenbr0)
2) transfer directly inside my server (xenbr0)

Is there a way to change that?
It seems the virtual interfaces are really 100 MBit and not only labeled so.

Therefor, is there a way to make them 1000 MBit ?

Regards,
  Steffen
