<div>You mention 012, but you do not mention what you're upgrading from. That can be helpful.</div>

</style>Hello,</div>
<div class="x_paddingtop x_paddingbottom">We experience slow network performance after upgrading for virtual machines.<br>
Copying from a system (physical machine) to the VM the copy speed drop from 85MB/s on release 10 to between 9 and 14MB/s. Both systems I upgraded experience the exact same symptom and use the igb driver.</div>
<div class="x_paddingtop x_paddingbottom">Both have Supermicro mainboards; X9DRD-7LN4F-JBOD and X10SLL-F. Copy tests are done between windows 8.1 and a Windows 2012R2 VM.<br>
Changing to virtio for nic as suggested in a previous email had no impact other than causing kvm to crash after copying ~400MB.
</div>
<div class="x_paddingtop x_paddingbottom"> <br>
Anyone else seeing this behavior?</div>
<div class="x_paddingtop x_paddingbottom"> </div>
<div class="x_paddingtop x_paddingbottom">I do see the X10SLL board has an e1000g nic also</div>
<div class="x_paddingtop x_paddingbottom">LINK MEDIA STATE SPEED DUPLEX DEVICE<br>
e1000g0 Ethernet unknown 0 half e1000g0<br>
igb0 Ethernet up 1000 full igb0<br>
</div>
<div class="x_paddingtop x_paddingbottom">I will switch over to that and test again.

Thanks,</div>
