> Libuv (which julia uses under the hood here) in theory has recently merged io\_uring support, but this is not exposed in this API (which is quite unfortunate from my POV).

It is very unfortunate, there was a great talk last JuliaCon about the traps of running an HTTP service, many of which were related to IO scheduling and would be alleviated (directly or indirectly) with io\_uring.

There was [interest](https://discourse.julialang.org/t/io-uring-support/48666) in using io\_uring prior to libuv gaining the feature, I imagine the barrier is a matter of manpower (I recall reading about libuv being an especially hairy dependency to upgrade?)
