<div class="moz-cite-prefix">Hello to all<br>
<br>
I'm experiencing very very strange (for me) scenario .<br>
I have installed kvm win 2012r2 server with all virtio drivers.<br>
<br>
At first test results were great :<br>
1. copying large file inside VM -> average 100MB/s virito
disk driver does great job (ide was 3 times slower)<br>
2. copying large file from VM (logged with rdp to VM and transfer
initiated from this VM) to another physical server -> approx
90MB/s alomost 1G saturated all the time <br>
<br>
BUT <br>
<br>
3. but when the transfer is initiated from the physical machine to
the VM then transfer speed lowers down to the 20MB/s (average)<br>
and VM CPU load goes up to 100% and blocks the whole server and
server stops serving data at all <br>
<br>
in VM performance viewer System and System-interupts occupie CPU
at most <br>
<br>
<br>
So we can say that network and disk performance when sitting at VM
is perfect but on the other side it cannot stand average network
traffic <br>
<br>
If you need more inputs from me please write a.s.a.p. :-)<br>
because customer is waiting for this problem to be solved <br>
so I thank you in advance for any hint/help <br>
<br>
