This doc kinda needs to say "TCP" somewhere, as it's very focused on TCP concerns - which is useful, people are mostly using TCP. The default UDP tunings are awfully low and as such are notably missing.
- leshow 3y agoDo you have any good resources for UDP tuning?
- BitPirate 3y agoThe typical painpoint is the low maximum buffer sizes. net.core.rmem_max net.core.wmem_max e.g. wireguard-go will hit those limits of not executed with CAP_NET_ADMIN.

It's older so some details have changed over time, but the concepts are still relevant. It also has a lot of useful search terms to get you started.
