That's a pretty good speed-up! I tried the same with http just now and got: $ time git clone http://orgmode.org/org-mode.git Cloning into org-mode... real 3m30.619s user 0m10.970s sys 0m0.750s so it improved on the 5 mins I was getting before by roughly 35%. My git time was pretty bad though (4.5 mins): I suspect clogging on the link to my ISP, so both of these numbers are probably suspect. I'll try again later tonight and see what I get. > I've set up a weekly cron job to run "git gc" on the org-mode repo. > Great! Thanks, Nick
