<div>Bryan, could you please elaborate your setup? do you see lag on your virt-host or in your VM's? what have you tried so far to test? can you please run:<br />
"iperf -s" on your server (or where do you see lagg)</div>
and "iperf -c $serveripaddress" replace $serveripaddress with your interface IP.</div>
and paste your output?</div>
<div>can you also descrie if this is a layer2 or layer 3 network?</div>
