My device came with Android 12 and I can say that I/O performance is _not_ abysmal. It is probably still worse than before the switch to FUSE, though. (I _could_ actually compare this with my Android 10 phone which has similar CPU specs and supposedly doesn’t use FUSE yet.)

Personally, I cannot really agree. I have one specific folder that contains two subfolders - one with 1000+ files in a single folder, and another one with 3000+ files. Syncing this folder for the very first time on Google Pixel 8 (which came with Android 14) takes 5+ hours.

On the other hand, the same folder syncs in ~5 minutes on an old Galaxy Tab running Android 7.
