On our repository packing used to take around 30 seconds, it now takes about 4 minutes. Which means that cloning the repository went from being slightly slow to pretty intolerable. I haven't dug into why this is but I'm pretty sure it's because this patch makes Git behave pathologically on repositories with a large amount of tags. git.git itself has ~27k revs / and ~450 tags, or a tag every ~60 revisions. Try it on e.g. a repository with a couple of hundred thousand revs and a tag every 10-20 revisions. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
