Run_debug.js only runs on test versions, right?

I’m kind of cheating here because my landing page is quite barebones and my app doesn’t use client side plugins for the most part but I can get okayish speeds. The only problem is that it takes forever just for the server to initially serve the request as you pointed out. Compared to the fastest websites that serve content statically this is still really slow. They need to work on this next and the expression composer next and stop fiddling around with the UI.
