Zero-copy network transmission with io_uring (2021)
That sounds interesting for routing applications.<p>I was just looking into building a custom router using an older PC and a dual-port 2.5GbE NIC. OpnSense sounds like a solid choice, but I'd prefer a Linux solution because the CPU is pretty beefy and wouldn't mind running a few Dockers on the side (yes, I know multi-purposing a router is a bad idea but meh).
