Phoronix: Btrfs Seeing Nice Performance Improvements For Linux 5.17

With the Btrfs file-system popularity ticking back up, that seems to be helping upstream enthusiasm and development efforts as with Linux 5.17 there is yet more exciting work...

This is great! Btrfs is my favorite filesystem for now with zstd.

That's cool, but I hope that the Zstd code will be updated to latest version too.
That way the combined improvements for BTRFS and Zstd will be great for users which use them together.
I really like all the performance improvements on this kernel.

Hopefully BTRFS RAID5/6 gets some loving as well.

The majority of Btrfs code is quite stable since years but performance is/was the only downside of this fs. Of course this is caused by the its very nature. Nonetheless is it good to see that we have reached the polish phase of this modern fs.

Hopefully this patch https://patchwork.kernel.org/project...?series=603266 from Goffredo Baroncelli will make it soon too.
(Allows to use SSD for metadata of HDD array, nice boost in performance for big filesystems and cold data)

quota needs some love as well: I've recently tried it with snapper but it constantly hangs my system with one core consuming 100% of the cpu and slowing everything else down to an unusable level.

Pretty much agree.
Though as a user who's creating a file browser I'm disappointed at Btrfs's extended file attributes support (a posix standard) - in that it only supports ~20KiB or less (per file) which most of the time isn't enough to attach a thumbnail to an image file which forces me to store them in a separate folder - which is slower to read and sync them to the respective image file when listing files in the browser and makes the file browser do extra housekeeping.

XFS on the other hand supports much larger extended file attributes which is why it's my favorite FS for now. Props to the XFS devs!

That already happened with 5.16:

Are you testing this problem on openSUSE? I ask because this was a problem until some time ago, however in recent times optimizations have been made in openSUSE, significantly reducing this problem.
On my system with Tumbleweed on SSD I only have occasional freezes, usually after big updates, but these freezes are really a few seconds long and due to snapshot cleanup.
