Tell me why I shouldn't use btrfs (lemmy.zip)

About a year ago I switched to ZFS for Proxmox so that I wouldn't be running technology preview.

Btrfs gave me no issues for years and I even replaced a dying disk with no issues. I use raid 1 for my Proxmox machines. Anyway I moved to ZFS and it has been a less that ideal experience. The separate kernel modules mean that I can't downgrade the kernel plus the performance on my hardware is abysmal. I get only like 50-100mb/s vs the several hundred I would get with btrfs.

Any reason I shouldn't go back to btrfs? There seems to be a community fear of btrfs eating data or having unexplainable errors. That is sad to hear as btrfs has had lots of time to mature in the last 8 years. I would never have considered it 5-6 years ago but now it seems like a solid choice.

Anyone else pondering or using btrfs? It seems like a solid choice.

How much ram and what is the drive size?

I suspect this also could be an issue with SSDs. I have seen a lot a posts around describing similar performance on SSDs.

64 gb of ecc ram (48gb cache used by zfs) with 2tb drives (3 of them)

Yeah it sounds like I don't have enough ram.

ZFS really likes RAM, so if you're running anything less than 16GB, that could be your issue.
