That would be a workaround but it doesn't explain why git.kernel.org deliveres torvalds repository without any notable counting and compressing time. Maybe it has something todo with the config I found inside the repository: http://git.overlays.gentoo.org/gitroot/exp/gentoo-x86.git/config It says that it isnt a bare repository. Before I forget. I was wrong that it is a single 910mb file. Somebody seems to have repacked it into 7 single packs.
