Okay, from a server POV it shrunk the 116MB folder down to just 7MB in less than two minutes (based on a trial run in my homedir), which is pretty sweet.
A trial with system-config-firewall.git went from ~20M to ~4M. I also did a trial run of anaconda.git and anaconda-images.git: anaconda.git: 183M (97745 objects) -> 64M (a third of the original size) real 26m18.050s user 23m9.395s sys 0m6.568s anaconda-images.git: 54M (1482 objects) -> 41M (didn't expect much here) real 1m57.944s user 1m43.466s sys 0m0.848s Maybe we should run git repack on the big repos on a bi/tri-monthly basis, and git gc (which is very fast - <1 minute on the anaconda repo for example) on a monthly basis. - Nigel _______________________________________________ Fedora-infrastructure-list mailing list Fedora-infrastructure-list@redhat.com https://www.redhat.com/mailman/listinfo/fedora-infrastructure-list
