How should I do this ? Can I do this on a live FS, and isn't this going
to double my on-disk used space (I have active snapshots...)

I believed that the "autodefrag" mount option was supposed to avoid the
need for manual defrags...?
Plus, with respect to snapshots, isn't this going to increase a lot my
used disk space ?

I'm not sure that "a bit" quicker will be enough, when I see my BTRFS is
currently about 8x slower than what ext4 user to...
