I think that it will still help with large enough rpms since rsync will
try to use parts of the files if they match names. (There options to
try to use files with similar names, but I don't think that is very
useful for compressed files since they change almost everywhere.)
The resources used are different though (bandwidth vs random disk IO) so
it could actually make things worse.
