WebMay 31, 2024 · Use Large Receive Offload (LRO) to reduce the CPU overhead for processing packets that arrive from the network at a high rate. LRO reassembles incoming network packets into larger buffers and transfers the resulting larger but fewer packets to the network stack of the host or virtual machine.

WebTCP segmentation offload (TSO) is an optimization technique that reduces the CPU overhead in TCP/IP-related network operations. With TSO enabled, a network internet controller (NIC) splits large data chunks traveling over a network into smaller TCP segments. Without TSO, the segmentation is performed by the CPU, which creates an overhead. WebTCP checksum offload and large segment offload are supported by the majority of today's Ethernet NICs. Newer techniques like large receive offload and TCP acknowledgment …
