zsh is extremely slow when I use zsh-git-promoty

[avatar-lavventura]

When I use solution from https://gist.github.com/msabramo/2355834#gistcomment-3533514 there is no slowness in my zsh shell.

But when I following lines into .zshrc and do enter in home folder everything becomes so slow and shell freezes. What is the proper way to load zsh-git-promoty? how could I make it not slow?

source /home/alper/zsh-git-prompt/zshrc.sh
PROMPT='%B%m%~%b$(git_super_status) %# '
