github.com/davidtos/JUring io_uring for Java. "Doing Random reads JUring achieves 33% better performance than Java NIO FileChannel operations for local files and 78% better performance for remote files."

The core of this work is now upstream in Linus's tree, and the per-fs bits have been rebased on top of that: git.kernel.dk/cgit/linux/log… xfs/btrfs/nfs should be fine to include, ext4 would ideally need an iomap conversion first.

epoll wait support for io_uring. This may seem like an odd thing, but it's handy for mixed use cases or event loop conversions. See the cover letter linked below for details: lore.kernel.org/linux-fsdevel/… and code: git.kernel.dk/cgit/linux/log…

We just merged support for incremental provided buffer consumption into our #iouring based transport in #netty. I can't wait to have all of this released soonish. github.com/axboe/liburing… github.com/netty/netty/pu…

Updated the Less Slow tutorial with web server/client examples using io_uring, POSIX, and ASIO! The ASIO version needs work, and the Linux kernel 6.0+ (with multi-shot recv, bundling, & zero-copy) can be improved too. Feel free to suggest patches šŸ¤— github.com/ashvardanian/l…

The networking side of the io_uring receive zero-copy support was finally merged, it's queued for the 6.15 kernel. See this merge for details: git.kernel.org/pub/scm/linux/… Now we just need to stage the io_uring side on top of that! Exciting to finally see this happening.

marcan on leaving the Asahi project: "No matter how much we did, how many impossible feats we pulled off, people always wanted more. And more." Yep this is basically ANY open source project. Doesn't matter what you give people, they will always complain about something.

The growth of data and need for increased power efficiency are leading to innovative storage solutions. Learn how (quad-level cell) QLC technology provides higher density, improved power efficiency, and better cost than existing TLC SSDs. engineering.fb.com/2025/03/04/dat…

Norman continuing to kill it on the io_uring networking side. This is the way, Nettty will be something to point to as a reference implementation of how it should be done.

All PRs sent to Linus for 6.15, in order: lore.kernel.org/io-uring/c8ee7… lore.kernel.org/linux-block/aa… lore.kernel.org/io-uring/12e0a… lore.kernel.org/io-uring/3ad3c… lore.kernel.org/io-uring/7994e… Some good stuff in there! First two are merged, last three were sent out today.

I am excited to finally announce the release of #netty 4.2.0.Final which is in the making for quite some time! This release comes with a lot of new exciting features, including the highly anticipated #io_uring support. See netty.io/news/2025/04/0…

Norman Maurer (@normanmaurer) 's Twitter Profile Photo

We are happy to announce the release of #netty 4.2.2.Final. This is our second release for the 4.2 release train, including bug-fixes, performance enhancement and new features. For all the details please read our release announcement: netty.io/news/2025/06/0…

agave-io-uring finally landed in agave (link below). Cleaning up accounts at startup goes from ~1 minute to 4s. Snapshot unpack is next. We're sending startup time to 0 in 2.3 šŸ“‰
