Improving performance through NetQueue
NetQueue is a performance technology that improves performance in virtualized environments that use 10 GigE adapters which is 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.
