tl;dr:
asynchronous IO (aio)

seems like pgetevents may not necessarily exist
can't say i'm particularly familiar with this subject, but here https://man7.org/linux/man-pages/man7/aio.7.html
seems useful enough, although i'm not sure why you'd prefer this over any other implementation. any anons around who've used this? care to weigh in?

i've never used io_uring myself, but seems cool.
iirc it allows for much faster read/write than standard read/write syscall.
don't remember how it works at all though. i need to look into this again at some point, and try writing some test code.

Those are very basic and are only useful for databases (afair they were added by Oracle). The biggest problem is that they only work in async way in O_DIRECT mode and only if buffer is properly aligned (block on submission otherwise).

Basically, they should be considred deprecated and were replaced by io_uring.

io_uring even allows you to write to files with no syscalls (after the initialization)

we'll be finishing before next year, but i'm open to checking out some other syscalls afterwards
