Description

Recent Linux kernel (5.1+) includes io_uring, a new non-blocking I/O subsystem, which might serve as a more efficient alternative to epoll. We could benefit from it and get a performance improvement in network I/O scenarios with high volume of concurrent connections and/or for fs operations.

Of course, in Node.js case we need changes made in libuv. There is an ongoing experiment aimed to add support for io_uring in libuv: libuv/libuv#2322

As this feature should be experimental (at least initially), io_uring mode could be activated under a new flag.

The goal of this issue is to improve visibility of the libuv experiment and gather some feedback.

    I’m happy to benchmark this if we have a matching Node PR. It’s very interesting!

    @mcollina no, we don't have a Node.js counterpart PR yet. But I hope to submit one once I find out status of the libuv PR. Will post any updates here.

    For the future engineer who will have to implement this, I created awesome io_uring as a collection of articles, tutorials, libraries and examples to help implement this interface.

    I'm going to close this because it's not actionable for node. io_uring support will likely come to libuv soon (I'm working on it) but it will be a transparent change to node.

    @espoal it was not merged into node.js just yet I guess. We'll need to wait for a libuv update here.

    @mcollina yes you're right :) Is there anything I can do to help with the process of integrating io_uring?

    Once there is a new release of libuv, this will be updated

    Node v20 released with libuv 1.46 if I'm not mistaken, will we see support in v21?

    @bnoordhuis The commentary around this functionality in libuv implies that libuv users will need to rework their code to take full advantage of the io_uring support. So unless I'm reading that wrong, "there's nothing for us to do" is not correct. You might get some benefit without doing anything, but there's more to be had.
