Well that's counter intuitive.... - reverting the original repo to one big pack speeds up the clone - adding a --local --reference mirror slows it down Timings: 14:41 ajb@vsbldhost/i686 [ajb] >time git clone git://engbot/repo.git test-clone-bigpack.git Initialized empty Git repository in /scratch/ajb/test-clone-bigpack.git/.git/ remote: Counting objects: 371220, done. remote: Compressing objects: 100% (88900/88900), done. remote: Total 371220 (delta 274586), reused 371220 (delta 274586) Receiving objects: 100% (371220/371220), 1.78 GiB | 20.10 MiB/s, done.

The first is the clone "hung" at around 22% checking out the files for ~ 10 minutes before finishing the remaining 70% in a few seconds. Secondly is seems in both cases the systime is quite high. -- Alex, homepage: http://www.bennee.com/~alex/ http://www.half-llama.co.uk -- 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
