If you are doing a local only copy (rsync isn't networking) then --whole-file is forced. There is no benefit of reading and checksumming files to reduce network transfer when there is no network transfer.
You said you were moving data to a remote server so I assume you are using a network mount of some kind to make it a local copy instead of letting rsync do the networking. Anyways, if rsync isn't doing the networking then forcing it to do a delta transfer would only make it take even longer.
