Is it? Last time I check, transfer between domU <-> dom0 (which is all on virtual interfaces, involving vif and bridge) on a somewhat old machine (an old Xeon 3.2 GHz) got me around 1-2 Gbps with 100% CPU usage. So when you have -- say -- a 10Gbps NIC, the physical NIC is no longer the limiting factor. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
