The following series builds on top of Barkalow's existing builtin-clone work, available in the "builtin-clone" branch at: git://iabervon.org/~barkalow/git.git This patch series teaches builtin-clone to create packed refs. Creating packed refs directly in clone (instead of creating loose refs and have the next "git gc" (re)pack them), makes cloning considerably faster on repos with many refs. In a test repo with 11000 refs (1000 branches, 10000 tags) I get the following numbers (Core 2 Quad, 4GB RAM running Gentoo Linux): - Current "next": ~24.8 seconds - Barkalow's "builtin-clone" branch: 1.47 seconds - "builtin-clone" plus this series: 0.31 seconds Although most of the speedup from current "next" is achieved by the builtin-clone work, there is still a considerable additional improvement from writing all refs to a single file instead of writing one file per ref. I expect the performance improvement to be much bigger on platforms with slower filesystem (aka. Windows). A side-effect of this series is that the cloned refs will not get reflog entries. I don't know how important these "clone: from $URL" entries are to people; I, for one, wouldn't miss them at all. Have fun! :) ...Johan -- Johan Herland, <johan@xxxxxxxxxxx> www.herland.net -- 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
