The kernel actually has a generic segmentation offload mechanism (called GSO) which is not limited to TCP. It turns out that performance improves even if the feature is emulated in the driver.
Using iPerf to Troubleshoot Speed and Throughput Issues IBM
WebThe iperf series of tools perform active measurements to determine the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, protocols, and buffers. For each test it reports the measured throughput, loss, and other parameters. WebIn this tutorial we learn how to install iperf on Ubuntu 20.04. What is iperf. iperf is: Iperf is a modern alternative for measuring TCP and UDP bandwidth performance, allowing the tuning of various parameters and characteristics. Features: * Measure bandwidth, packet loss, delay jitter * Report MSS/MTU size and observed read sizes. harry selfridge

Web18 nov. 2024 · iPerf, which is short for Internet Performance Working Group, is an open-source speed test and network performance measurement tool. The mechanism is fairly simple: it creates TCP and UDP streams, and sends traffic from one host to another, then reports the maximum bandwidth to the user.
