I have moved big chunk of data between two of subvol on btrfs volume. Well… I forgot to use btrfs feature and used standard mv command. It took lots of time. So… more optimal way for this operation on btrfs volume is to use reflink:
cp -pr --reflink=always subvol1/dir subvol2/dir
rm -rf subvol1/dir
