io_uring support is on our roadmap. It may be implemented someday, but there is no specific guarantee for that.

epoll should suffice to support the most cases, thus io_uring shouldn't be so pressing at this point. Are you experiencing some performance bottlenecks currently?

@panjf2000 sry for late reply.
my only perf bottleneck is without io_uring.

this benchmark is like an eyesore, it makes my gnet implementation looks terrible.

i'm only looking at gnet once in a while to solve 2 issues:

1. io_uring
2. http2 integration / cloudwego/hertz replacement to netpoll

gnet is one of the best work for golang. need io_uring to complete it.

well done and thx. cant thank u enough.

p.s : 1 last thing, hope u can reduce heap obj for gnet after io_uring is done.

@panjf2000 can u pls help with standardizing the example for use with tls? it's already there but there doesnt seem to have support or example on how to use it.

please support it with examples for https / tcp connection:

can u take a look into this? i'm trying to upgrade redhub to use v2 and tls:

I think #565 is still WIP.
