Hello,
I have one virtual server Win2012Std as host on esxi 5.5. HW server is DELL T110 II.
When I launch virtual server everything is OK and LAN speed is over 40-70 Mb/s.
But after a few day (between 7-14) the speed go down on 100-400 Kb/s.
Sometimes help me, when I disable and enable network adapter in Win2012 and speed increase to normal state.
Certain help is stop and start virtual host or restart windows 2012 server, but after a few day error with LAN speed again.
Driver on host I have VMXNET3.
This problem I have on two independence server (both DELL T110).
That you for some help...
P.
