NetQueue is a type of performance technology that improves the performance of virtualized environments that use 10 GigE adapters supported by VMware. NetQueue takes advantage of the multiple queue capability that newer physical network adapters have. Multiple queues allow I/O processing to be spread across multiple CPUs in a multiprocessor system. So while one packet is queued up on one CPU, another packet can be queued up on another CPU at the same time.
To step through this recipe, you will need a running ESXi Server with SSH enabled and an SSH client (Putty). No other prerequisites are required.
NetQueue is enabled by default. Disabling or enabling NetQueue on a host is done using VMware's vSphere Command-Line Interface (vCLI).
To enable and disable this feature, perform the following activity:
- Log in to the ESXi host using an SSH client (Putty).
- Now run the
esxcli system settings kernel
with the following command:
~ # esxcli...
