The CPU has to process fewer packets than when LRO is disabled, which reduces its utilization for networking especially in the case of connections that have high bandwidth. TCP Segmentation Offload (TSO) TSO on the transmission path of physical network adapters, and VMkernel and virtual machine network adapters improves the performance of ESXi hosts by reducing the overhead of the CPU for TCP/IP network operations. When TSO is enabled, the network adapter divides larger data chunks into TCP segments instead of the CPU. The VMkernel and the guest operating system can use more CPU cycles to run applications.
