We run BTRFS on our work laptops and have been for a few years now. Keep in mind that we're only 4 devs, so our sample size is small, but we haven't had any issues with it so far and it's been very pleasant to use so far! We published our internal doc for how we install our Arch setup with fully encrypted BTRFS if anybody is curious. Happy to answer any questions too! https://www.lunasec.io/docs/blog/arch-linux-insta…

i am running fedora on encrypted btrfs, on top of a mirror raid, and i have a lot of problem with the performance of the disk. I/O frequently hangs the GUI for a few seconds. throughput is fine once it gets going, but random access to many files appears to be an issue. searches pointing to btrfs on encryption being slow, but i think the raid is also a factor.

Check both of these links, I added the configurations to my laptop with BTRFS + NVME SSD + encryption and it's snappy. https://wiki.archlinux.org/title/Dm-crypt/Specialties#Discar... https://wiki.archlinux.org/title/Dm-crypt/Specialties#Disabl...
