All you never wanted to know about creating fast socket I/O on #Linux. Unless you are a real geek.
A small, ultra-high performance publish-subscribe server doing kind of TCP #multicast using #sendfile, #io_uring, #splice, (mapped) files, and #fallocate for file hole punching.
Saturating a 10 Gbps link with useful data with just 8 cores.
A beautiful writeup for anyone into fast Linux networking. Not just for #ATproto
