however.)
#### Alternative implementation using io_uring
[io_uring]: https://en.wikipedia.org/wiki/Io_uring
[glommio]: https://github.com/DataDog/glommio
There is an alternative implementation that utilizes [io_uring] by running on
[glommio]. It only runs on Linux and requires a recent kernel (version 5.8 or later).
#### Performance

More details are available [here](./documents/aquatic-udp-load-test-2021-11-08.pdf).
Since making this benchmark, I have improved the mio-based implementation
considerably and removed the glommio-based implementation.
