The one you are referencing is to the loopback device on the VM, not VM to VM.
recap: VM loopback device on VM = 26 gbps VM traffic is limited to 10gbs ( actual data is ~5 per 10G link on host ) Host to Host is 18 gbs ( actual data is ~9 per 10G link on host ) Host bond0 = 20gbs link speed **Host Openvswitch link speed = 10gbs ** This is the one I am most curious about On Sun, May 8, 2016 at 10:56 PM, Scott Lowe <scott.l...@scottlowe.org> wrote: > Please see my responses inline, prefixed by [SL]. > > > > On May 8, 2016, at 4:35 PM, ed bond <celpa.f...@gmail.com> wrote: > > > > Scott, > > > > I agree.
