> io_uring relies on a pool of independent kernel threads performing operations on buffers Do note that this setup was rewritten at kernel version 5.13 or something like that, and the current model seem to be some sort of hybrid variant of kernel and userspace threads. From what I gather it was a huge improvement compared to how it was before.
