Phoronix: F2FS With Linux 5.18 Boasts Performance Improvements, Faster Recovery After Power-Cut

Jaegeuk Kim submitted the Flash-Friendly File-System (F2FS) updates on Monday that today were merged to mainline for the Linux 5.19 cycle...

I'm using F2FS on a daily basis with compression enabled and it goes pretty well. Not many X-Files on my end.

F2FS transparent compression isn't like BTRFS or ZFS, it's for reducing writes.

Still, reads will be faster, given a powerful enough CPU, due to the fact you are reading less data from the disk, which is the biggest bottle neck. Writes are considerably slower though.

Sadly, even reads are slower based on some of my Intel 660p tests/workloads.

Its way less severe than the btrfs zstd performance hit, but still...

So if I'm reading this right, they ignored the feedback until Linus saw the code. A few versions ago F2FS made the system unbootable. I like F2FS and I'm using it for 2+ years now with no issues, but I always come on Phoronix to check what the next version might do to my system (So far this method has worked fine). I hope they can improve their testing in order to avoid more serious issues in the future.
