GIT performance issue

Hi All,

We are having low speed clones and transmission through git to different locations from US. We are suspecting it as protocol issue. Our git servers use openssh and Users use openssh or putty on their PC’s for day to day activities.

Is there any underlying config changes we need to make to solve slow clone issues?
Is there anyway we can specify the large SCP buffer size inside GIT, is it possible?

Thanks
PRS
