The results are under
"http://lists.debian.org/debian-devel/2001/debian-devel-200106/msg01859. html" It just shows 2 days but the test went on for about a week with similar results. While uncompressed is still the best for rsync download, it shows a significant reduction (more than 50%) against a normal compressed Packages.gz. Similar savings are possible if this is applied to Debian packages. O.
