Io Uring
I've tinkered around with io_uring on and off for the last couple years. But I think it's really becoming quite cool (not that it wasn't cool before... :)). This was a really interesting post on what's new https://github.com/axboe/liburing/wiki/io_uring-and-networki.... The combination of ring-mapped buffers and multi-shot operations has some really interesting applications for high-performance networking. Hoping over the next year or two we can start to see really bleeding edge networking perf without having to resort to using DPDK :)

Why you should use io_uring for network I/O
Thought I was doing something wrong at first, but after looking at examples and code, I just wasn't able to reach the epoll numbers. Looking on the Github page, there a few issues there with people who found the same thing, with their own examples. #1, #2

Use io_uring for network I/O
To address my own silly questions, yes, one should use the new fixed buffers described in this document: https://github.com/axboe/liburing/wiki/io_uring-and-networki...

Put an io_uring on it: Exploiting the Linux Kernel
> Network IO discussion: https://github.com/axboe/liburing/issues/536
I see an issue with a narrative but zero discussion at that link.
Furthermore, your io_uring benchmark being utilized in that issue isn't even batching CQE consumption. I've submitted a quick and dirty untested PR adding rudimentary batching at [0]. Frankly, what seems to be a constant din of poorly-written benchmarks portraying io_uring in a negative light vs. epoll is getting rather old.
