Yes,  i saw the creation date on the window of the configuration NIC.
Tested in Dell poweredge 9500 and Dell R720 (each one with with 2 sockets)

And if you want more speed of network, please see this link about of "I/OAT 
DMA Engine", and if you can, also answer my questions.

mine was a dell r620, 2x intel 8 cores, so almost same than you.

but win2012r2.

I'll do tests with win2008r2 next week.

(are you sure that virtio-net driver is correctly upgraded to last version 
?)

I have tested with:
Server: Dell r720 (New)
PVE latest version with kernel 3.10 version
RAM total in Hardware: 256 GB.
RAM for the Win2008R2 SP1 VM: 248 GB.
Processors: 2 sockets of 10 cores each one (20 threads with Hyperthreading)

Maybe numa (in Bios hardware DELL R720 configured) have something that see
in this topic.... the bsod (that appears sometimes)

I have tested with win2012R2,

I don't have BSOD, but network don't work when multiqueue is enabled.

I'll try to dig a little more.

Hi

I have tested this:

Win2008R2 SP1 VM +
net0: ......,queues=<numberofqueue>
----------------------------------------- 
= bsod

With 8 and 4 numbers of queues, it isn't stable.
