This is a repost of the awesome post from interrobeng.com where he was able to speed up GIT pull from Singapore EC2 against Github from 5~ seconds to 1~ second or so for the basic configuration and even less than a second after all the other tweaks are applied.
I used same basic configuration as well on my Linode VPS in Dallas, Texas against Github which speed up from 0.8~ second to 0.3~ second using just the basic configuration which is all I need. Below is the configuration change:
ControlMaster auto ControlPath /tmp/%r@%h:%p ControlPersist yes
It can go even more faster but I don’t know if there are drawbacks though.
Read the full post for the rest of the tweaks.
Enjoy and share the awesomeness.
