Gitlab really slow with a bunch of tags / branches

Created by: netdata-be

As you can see getting this request takes about 30 seconds. I'm using the latest master branch and apache/passenger combination.

Is when I look to top I can see ruby taking 100% CPU Is this expected behaviour ?

This project has +- 200 tags and +- 50 branches
