I'm not sure the full purpose of --whole-file.  Maybe if you copy of lots of
teeny-tiny files, it may eliminate the wasted time of diff checks.  But for
large files, I don't see the point of using --whole-file.  And if the
destination file doesn't exist, well rsync does a "whole-file" copy anyway.

rync just syncs bits by the divide and conqueror method regardless of the
file being text of binary - it's really fast.

Don't use --whole-file if you're doing syncs over slow wan links like a T1.
