Best Filesystem for NAS? (self.selfhosted)

A year ago I set up Ubuntu server with 3 ZFS pools on my server, normally I don't make copies of very large files but today I was making a copy of a ~30GB directory and I saw in rsync that the transfer doesn't exceed 3mb/s (cp is also very slow).

What is the best file system that "just works"? I'm thinking of migrating everything to ext4

EDIT: I really like the automatic pool recovery feature in ZFS, has saved me from 1 hard drive failure so far

ZFS is by far the best just use TrueNAS, Ubuntu is crap at supporting ZFS, also only set your pool's VDEV 6-8 wide.

I was thinking about switching to debian (all that I host is in docker so that's why), but the weird thing is that it was working perfectly 1 month ago

Maybe your HBA is having issues? or a Drive is Failing? have you done a memtest? you may need to do system wide tests, it can even be a PSU failing or a software Bug.

also TrueNAS is built with Docker they use it heavily something like 106 apps, Debian has good ZFS support, but you will end up doing a lot of unneeded work using Debian unless you keep it simple.
