Use TCP Segmentation Offload (TSO) in VMkernel network adapters and virtual machines to improve the network performance.

TSO on the transmission path of physical and virtual machine NICs improves the performance of ESX/ESXi hosts by reducing the overhead of the CPU for TCP/IP network operations. When TSO is enabled, the NIC divides larger data chunks into TCP segments instead of the CPU. The host can use more CPU cycles to run applications.
