All the io_uring benchmarks regressed 20-45% after it. I haven't tested on v6.1 yet. It should basically make the behavior the same as before once you apply the patch, so please pass on the patch that you applied for 5.15 so we can take a closer look. Also, please don't top post. Replies go below the context, that's normal OSS etiquette. Just like I did in the first one, and in this one. -- Jens Axboe
