" We have no problem getting 900Mb/s in/out of xenU's and the wire on our
" 2.4GHz Xeon systems (regardless of whether using uniprocessor, SMP or
" hyperthreading).
Hmmm, I'm certainly having a problem getting over 500Mbps into xenU.
I ran another set of tests, this time between two
identical Dell 1650s, (one 1.4GHz PIII, 2GB ram, e1000 NICs) directly
connected to a Catalyst 4005.
Running a 10sec iperf run, I got these bandwidths:
Stock linux-2.4.25 (no patches or network tuning)
941 Mbps stock -> stock (identical speed both directions)
941 Mbps stock -> stock
Running 2.4.27-xen0 on xen-2.0 before starting xend or the network script:
894 Mbps xen0 -> stock
622 Mbps stock -> xen0
After starting xend, which brought up the bridge:
734 Mbps xen0 -> stock
524 Mbps stock -> xen0
After starting one xenU, xen0 was a touch slower:
729 Mbps xen0 -> stock
515 Mbps stock -> xen0
530 Mbps xenU -> stock
470 Mbps stock -> xenU
427 Mbps xenU -> xen0
253 Mbps xen0 -> xenU
After taking the vif off the bridge
with 'brctl delif xen-br0 vif1.0':
463 Mbps xenU -> xen0
312 Mbps xen0 -> xenU
