Hi,

I am doing backups using btrfs snapshots with this kind of (dir/subvol)
layout.

backups(btrfs-root)
machine1 machine2
work(rw) day1(ro) day2(ro)... work(rw) day1(ro) day2(ro)...

There are tens on machines and hundreds of daily snapshots total and I can
see slowness.

Now I am wondering which one is better. Should those machine level
"directories" be directory or subvolume?
