XFS / EXT4 / Btrfs / F2FS / NILFS2 Performance On Linux 5.8

[uxmkt]

ext4 being slow is not a regression, it's a systemic issue that was already known in 2012, cf. https://youtu.be/FegjLbCnoBw?t=1242

Any guess to why the COW filesystems are so bad at app startup? I would assume the issue is that need to write to several log/cache files, read performance aint bad, and checksums shouldn't cost that much.

atime updates maybe?

XFS isn't that finicky anymore, assuming your hardware is working properly (ie no unstable overclocks/faulty RAM/storage/cables etc.). You should always back up your data though, no matter the filesystem.

Glade to see BTRFS performance is good enough when compared with EXT4. I'm using BTRFS on every desktop and rpi 4 right now, for it's snapshot and subvol features, really useful and addictive indeed; one can install various distros or even mix PC/Rpi distros on same disk/partition via different BTRFS subvols.

Btrfs and compression is great on rootfs on SD cards. Speeds things up and helps with wear.

It's nice to see just how amazing XFS still is compared to more 'modern' file systems

XFS started out very modern for its time. It is still quite modern, in my opinion.

Anyway, nothing much has changed since the 1980s in computer science. If it was good then, it's still good now.

Yet another *facepalm* for my decision to move all drives from XFS to EXT4, back when I got my first SSD.

Well I tried using F2FS and while it works, I had to disable automount because it required a file system check at boot time, which then slowed down boot time. Sigh.

I think I'll just do XFS in the future, see how it goes.

Current OpenZFS in Ubuntu doesn't support Linux 5.8 kernel, looks like some compat patches were added to OpenZFS Git just a few weeks ago. Plus this was a comparison of mainline file-systems with a focus on Btrfs.

Understandable, but let me add my +1 for running including ZFS _when possible_ in these comparisons. (I use only ZFS everywhere except for /tmp-like storage)

Is f2fs stable enough for daily usage?

I used F2FS for months last year on my Gentoo installation. Zero problems!
