[pve-devel] win8r2 virtio net problems

>>I'll do tests on a xeon to compare too.

on my old xeon, ( 2 cores 5110  @ 1.60GHz)

with netperf:

win2008r2 -> host : 1,5gbit/s
win2012-> host : 5gbit/s  (seem big improvement in lso)

host -> win2008R2 : 1gbit/s
host ->win2012 : 1gbit/s

win2008R2 -> win2008R2 : 1gbit/s
win2012-> win2012 : 1gbit/s
win2008R2-> win2012 : 1gbit/s



same result with my 64cores opteron

>>strange, I just get 300mbit/s (intel xeon E5-2620 12 cores) 
(how many cores in the guest ?) 

I'll do tests on a xeon to compare too. 




Just have done test with ntttcp, I can't get more than 230mbit/s 
(2 guest 16 cores, -m 16,..)

strange, I just get 300mbit/s (intel xeon E5-2620 12 cores)
