RE: [Xen-users] Problems with GPLPV network latency

["Nick Couchman" <Nick.Couchman@xxxxxxxxx>]

And they're all running the same version of Xen and the dom0 kernel?

At this point, I'm just trying to highlight differences that may be causing 
this.  If you're running identical kernels, I highly doubt the bridge mode is 
to blame, since that's part of the dom0 kernel.  If the kernels are different, 
than it could be the bridge module or the module for the specific network 
chipset you're using.

When you say the MBs are slightly different, do you know what those differences 
are?
