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.

Great!
