[Alexandre DERUMIER]

Here my results
---------------

tested with iperf
https://iperf.fr/download/iperf_2.0.5/iperf-2.0.5-3-win32.zip
https://iperf.fr/ said that performance issues has been fixed in last version


without multiqueue
--------------------
iperf -c x.x.x.x -i 1 -t 100

vm->host
--------
  0.0- 1.3 sec   860 MBytes  5.37 Gbits/sec
host->vm
----------
[  3]  3.0- 4.0 sec   290 MBytes  2.43 Gbits/sec



with multiqueue = 2  (4 almost same results)
-------------------
iperf -c x.x.x.x -i 1 -P 2 -t 100    (-P for more parallel connections)

vm->host
--------
[SUM]  0.0-19.8 sec  15.1 GBytes  6.56 Gbits/sec
host->vm
----------
[SUM]  9.0-10.0 sec   510 MBytes  4.28 Gbits/sec


1vhost-process is created by multiques.


So, as expected, multiqueue improve inbound traffic.
