Subject: [Xen-users] NIC Offloading Confusion

I have been using the built in Xen Paravirt NIC drivers for paravirt
networking and had bad performance until I disabled all offload setting
on the bridge and paravirt nic (From Dom0).

There are 2 related questions I have, where should I be tweaking the
offload settings, the Dom0 Physical NIC, The Bridge or the DomU NIC?
Which settings in particular tend to cause trouble? (I just disabled all
of them because this was a server that is in use that I converted to
paravirt dirvers)

Does anyone have any Ethtool -K recommendations for a Xen,
Redhat/Centos, Intel PCI-Express and Intel Legacy PCI drivers?

Thanks,

Rob
