Thank you for the feedback on the paper and the guidelines. Regarding kernel versions: io_uring is under very active development (see the plot at https://x.com/Tobias__Ziegler/status/1997256242230915366). @axboe and team regularly push new features and fixes out. Therefore, some features (e.g., zero-copy receive) require very new kernels. Regarding deployments: Please refer to the other discussions regarding cloud deployment and containers. Besides the discussed limitations, some features (e.g., zero-copy receive) also require up-to-date drivers, and hence, results are also sensitive to the used hardware. Note that the three key features of io_uring (unified interface, async, batching) are available in very early kernels. As our paper demonstrates, these are the key aspects that unlock architectural (and the biggest per) improvements.
