Multi-queue support

Multi-queue can scale network performance with the number of vCPUs. Multi-queue can also create multiple TX and RX queues. Modify the .vmx file or access Advanced Settings to enable multi-queue.

To enable multi-queue open the .vmx file and add the following parameter:

ethernetX.pnicFeatures = “4”

To enable receive-side scaling (RSS), from the ESXi CLI enter:

$ vmkload_mod -u ixgbe

$ vmkload_mod ixgbe RSS=”4,4,4,4,4,4”

For the best performance, you should also additional CPU threads for each ethernet/vSwitch device. This is limited by the amount of spare CPU resources available on the ESXi host.

Open the .vmx file and add the following parameter:

ethernetX.ctxPerDev = “1”
