Reason for closing:  Deferred
Additional comments about closing:  No more testing-snapshots. Doing this for final-snapshots does not make sense. See test for 1 week, imagine now for 1 month...

zsync does not make any sense in our case. See zsync documentation.

Our ISOs contains few big compressed files (*.sfs), these files are compressed with lzma(xz) algorithm.

I just tested it to get some real numbers.

archlinux-2012.02.28_04-00-01-netinstall-x86_64.iso -> archlinux-2012.03.06_04-00-01-netinstall-x86_64.iso (Target 17.9% complete) [1 week]
archlinux-2012.03.05_04-00-01-netinstall-x86_64.iso -> archlinux-2012.03.06_04-00-01-netinstall-x86_64.iso (Target 49.5% complete) [1 day]

maybe...
