Apparently this was an exceptional case, I've been regularly repacking (git-repack -a -d) and more recently cleaning (git-gc) this repository since the early days of git (Mid 2005). This should therefore be compared to the first pack file generation and I don't believe that you will ever get that factor on any repository created with a more recent version of git. There is however a difference between even recent versions of git, the pack for the linux kernel is today: $ ls -l .git/objects/pack/ total 182140 -rw-r--r-- 1 paubert src 11887736 Jun 1 12:48 pack-dee9b723599778238ea89166583a609b415037bd.idx -rw-r--r-- 1 paubert src 174426948 Jun 1 12:48 pack-dee9b723599778238ea89166583a609b415037bd.pack with git (repack -a -d -f) from Debian Etch (1.4.4.4), and: $ ls -l .git/objects/pack/ total 164232 -r--r--r-- 1 paubert src 11887736 Jun 1 12:24 pack-dee9b723599778238ea89166583a609b415037bd.idx -r--r--r-- 1 paubert src 156105549 Jun 1 12:24 pack-dee9b723599778238ea89166583a609b415037bd.pack using a freshly compiled git (1.5.2.146.gb75c6) and git-gc --aggressive. That's in the ballpark of the 10% (actually a bit better) announced in the 1.5.2 release notes. Gabriel
