alt Hacker NewsI've not yet tested the shared buffers for my io uring based web server, but that's because instead of reading from a file and writing, i send directly from a mmaped region.
But really, I want to sendfile with io_uring, but that's not supported yet.
My writeup, with extra buzzwords like Rust and kTLS: https://blog.habets.se/2025/04/io-uring-ktls-and-rust-for-ze...

FYI you can use sendfile ish with uring, since splice(2) is implemented. Not as user friendly as sendfile, but should work fairly similarly.
