Hi, I have 2 ESX hosts with 10Gb cards in them. I have a vSwitch configured with the NICs added, they are all showing 10000 full. The physical switch is showing connected at 10Gb as well
I added 2 VM's with vmxnet3 NICs on the same host to the port group. Inside the VM's, I see vmxnet3 Ethernet Adapters in both, and they both show connected at 10Gb speed.
However, if I take a 3 GB file, and copy it between the VM's, it takes anywhere from 30-50 seconds, which puts my speeds at something like 480-800Mbps, obviously nowhere near 10Gbps.
I should also mention that there is nearly no other traffic on this ESX host, it's still in the testing phase so has only a handful of VM's on it.
Can anyone suggest what I might have done wrong? I assumed when I saw the NIC connected at 10Gbps inside the VM that everything was hunky dory, but these speeds suuuuck.
