Speeding up Git with SSH Config

I’ve been snooping around Paul Irish’s dotfiles and discovered this gem. I instantly noticed the difference and absolutely needed to share this with the rest of the world!

# copy to ~/.ssh/config

Host github.com
	ControlMaster auto
	ControlPersist 120

Host *
	# Always use SSH2.
	Protocol 2

	# Use a shared channel for all sessions to the same host,
	# instead of always opening a new one. This leads to much
	# quicker connection times.
	ControlMaster auto
	ControlPath ~/.ssh/control/%r@%h:%p
	ControlPersist 1800

	# also this stuff
	Compression yes
	TCPKeepAlive yes
	ServerAliveInterval 20
	ServerAliveCountMax 10
