Ted Ts’o sent out the EXT4 updates today for Linux 6.11. He explained in that pull request:
“Many cleanups and bug fixes in ext4, especially for the fast commit feature. Also some performance improvements; in particular, improving IOPS and throughput on fast devices running Async Direct I/O by up to 20% by optimizing jbd2_transaction_committed().”
On the last system I put together I used xfs because I was thinking ext4 development was waning. TBH I can’t really tell the difference in my regular usage.
Word on the street is that xfs sometimes corrupts files, but I’m not sure if that’s true anymore.
Maybe on the next system I’ll be back to ext4.
Btrfs is newer and has more features
