Phoronix: Btrfs In Linux 6.5 May Bring A Cumulative Performance Improvement

Bcachefs hopes to finally merge in Linux 6.5 while for those wanting a mature Linux file-system with all the bells and whistles, Btrfs is a good candidate worth considering. With Linux 6.5 there is a continuation of the recent Btrfs trend around performance improvements...

Wake me up when they merge and switch to the new on disk format.

Would be nice to see some benchmarks comparing XFS x EXT4 x F2FS x BTRFS x ZFS x BcacheFS on the upcoming linux 6.5.

block group tree has been available for a few releases, you need a btrfs-progs compiled with experimental to turn it on though.

I remember there was a working progress page for this, but cannot find it anymore.
do you have any link?

The new on disk format is a must to get things like quotas+snapshots usable.

check user visible changes here:

i think this is the page you were thinking of. This block group tree was split out from the larger extent v2 work, since it was ready to go, and gives much needed improvements. I'm really not sure what the state of this bigger effort is.

my mount time went from 5 minutes to 5 seconds.. prior to that I had to keep increasing systemd timeout settings (DefaultTimeoutStartSec) to keep up with how bad it was.

thank you!

the page I remebered was another one. Maybe was on github?
anyway these two links are very useful!

didn't know they already merged a lot.

So when should I switch from ext4 for my root partition, is the file system ready yet and is it SSD friendly in terms of the amount of writes compared to ext4?
