Git-project scanning slow


I was using git-project for quite some time, but now there seems to be something wrong with the package or my setup. After hitting ctrl-alt-o scanning of my repos takes very long. Each time I use crtl-alt-o the package scans my repo which makes atom and my whole computer unresponsive.

The last commit is from 2015. Is the project maintained. Shall I use another project package?
