Hello, Here a first experimentation of IO_URING on certificate loading. It targets heavy users of certificates (several thousands), most likely public hosting operators. I believe it could be a post v2.2 material if people are interested. I tried to make it the less invasive possible in ssl_sock.c to it remains maintainable.
Other experimentation are ongoing around epoll operations (I'm thinking about alternative way for busy polling) but that something that I want to extend later with more serious testing. I also recently got some crazy ideas around traffic duplication to make use of async, but that's another story. see also https://kernel.dk/io_uring.pdf for more info about io_uring.
