Proud to have @tigerbeetle.com as our partner for the Radical Cup NA season! I have the greatest respect for how TigerBeetle does engineering, it resonates deeply with how I work. We have collaborated on the software front, now we take this partnership to the track!
TigerBeetle@tigerbeetle.com · 5mo agoJens @axboe.bsky.social put Linux in the fast lane with io_uring. His son Jonas takes the need for speed to the track. And TigerBeetle is proud to partner. Catch Jonas at Sebring this weekend for the Radical Cup North America season opener!
TigerBeetle 0.16.75 is released! - Use transparent huge pages on Linux for a small performance boost. - Fix a fast path optimisation which wasn't being taken. github.com/tigerbeetle/...
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 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/linu... Now we just need to stage the io_uring side on top of that! Exciting to finally see this happening.

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-fsdeve... and code: git.kernel.dk/cgit/linux/l...

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/l... xfs/btrfs/nfs should be fine to include, ext4 would ideally need an iomap conversion first.

Jens Axboe@axboe.bsky.social · 2y agoPosted v8 of the uncached buffered IO patchset. This should be fine for merging at this point, let's hope we can make the 6.14 kernel release. lore.kernel.org/linux-fsdeve... Separate branches exist for the core support and fs support, see the cover letter for details.

Interesting memcached experiment from @UWaterloo showing some nice wins. Maybe 2025 will be the year of io_uring networking. git.uwaterloo.ca/lseo/io_uring
