I've done tests some time ago that showed a 4.8 factor to reduce bandwidth needs for RHEL update releases. Big drawback will be the need of the previous packages, so this might again be only something for a local server to download updates, but not for normal client machines. Still the savings look very nice, so I think we should continue looking at this. greetings, Florian La Roche
