Web41.1. Overview. Generic Segmentation Offload (GSO) is a widely used software implementation of TCP Segmentation Offload (TSO), which reduces per-packet processing overhead. Much like TSO, GSO gains performance by enabling upper layer applications to process a smaller number of large packets (e.g. MTU size of 64KB), instead of processing … Webtso on off Specifies whether TCP segmentation offload should be enabled. ufo on off Specifies whether UDP fragmentation offload should be enabled gso on off Specifies whether generic segmentation offload should be enabled gro on off Specifies whether generic receive offload should be enabled ...

WebFeb 6, 2024 · gso. GSO (“Generic Segmentation Offload”) is a performance optimization which is a generalisation of the concept of TSO . It has been added into Linux 2.6.18. Taken from Herbert Xu's posting on linux-netdev. Many people have observed that a lot of the savings in TSO come from traversing the networking stack once rather than many times …
WebTCP segmentation offload (TSO), or Large send offload (LSO), reduces the CPU usage of the host system in high-bandwidth outbound network connections. In TSO, data segmentation is offloaded to the NIC that divides the data into the default maximum transmission unit (MTU) size of the outgoing interface.
