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().”
Mine too. I could not bring myself to adopt a new or different FS at the moment. I wonder what “fast devices” and “slow” in this context means.
NVME SSDs vs HDDs, perhaps?
