From wiki: "If you find any behavior .... performance issues, or
have any questions about using Btrfs, please email the Btrfs mailing list "
Here is performance report:
Current debian stable distribution:
# cat /etc/issue
Debian GNU/Linux 11 \n \l
# uname -a
Linux pegaz 5.10.0-18-amd64 #1 SMP Debian 5.10.140-1 (2022-09-02) x86_64
GNU/Linux
# btrfs --version
btrfs-progs v5.10.1
It is backup server. It has 50 subvolumes:
# btrfs sub list / | wc -l
