You are right Jakub, I swapped the last two results, Test on small packets with UDP (iperf3 -t 100 -l 700 -u -b 0 -c *) - With pre-computed header: UDP TX: 16.4Mbit/s - Without UDP TX: 15.8Mbit/s -> 4.3% improvement -- Clément Léger, Embedded Linux and Kernel engineer at Bootlin https://bootlin.com
