Why does NewRelic report 100 constant cache invalidations per request on gitlab.com
I am not 100% sure what it means to have 'constant cache invalidations' but 100 per request sounds like a lot to me.
The only thing I found on the internets so far is this discussion, where some gem we are not using had an impact on this number:

So my hunch right now is that somewhere in GitLab some unfortunate meta-programming is going on that slows down each request. Maybe something with routing?
