Thanks. Testing again and leaving the network out of it with
$ time rsync --verbose -ac /path/dir/ /other/disk/dir/
before:
1m19.74s real 0m13.31s user 0m17.57s system
1m19.64s real 0m13.82s user 0m18.36s system
1m19.51s real 0m14.12s user 0m18.31s system
after:
1m09.00s real 0m01.06s user 0m14.97s system
1m09.04s real 0m00.99s user 0m14.70s system
1m09.01s real 0m01.01s user 0m15.25s system
That's about 9% time saving.
