- anarazel 5y agoPartially that can be amortized with io_uring... At the cost of some complexity, of course.
- MichaelMoser123 5y agoio_uring was added to linux 5.1, that was in 2019. I have to admit that i didn't yet have the chance to use it. https://en.wikipedia.org/wiki/Io_uring https://en.wikipedia.org/wiki/Io_uring Did you use io_uring? Is its performance much better than or comparable with using aio_read/aio_write for block io? (i did use async io for block io).
