Hi,

I am using xen 3.1.3 on a Celeron, a netbsd 4.0 dom0, and netbsd 4.0
and slackware 11 (with 2.6.18.8-xen kernel) domU's, and a bridge to
communicate between those. I noticed traffic between (both ways)
netbsd dom0/domU is rather slow (4Mb/s max), and traffic from the
linux domU to dom0 is about 18Mb/s, while traffic from dom0 to the
linux domU is rather slow again (4Mb/s max). Any idea why? I can of
course provide more info if necessary/wanted. I'm not sure this is the
same issue described in a recent post ("DOMU to DOM0 performance
issue"), since there are too many different factors.

Thanks in advance,
Michai Ramakers
