Isn't this whole article completely specific to the Google App Engine use case? Google App Engine loads all of your static files onto shared servers in use by many other users and builds up some kind of lookup table to access requests. It's not entirely clear how they've architected this, but it's obviously unlikely that they store everything in RAM.
So the most likely cause for the random slowdowns are when javascript files are loaded from disk to ram or some similar process.
For most cases, you'd have your javascript files sitting in-ram on a dedicated static file server cache such as apache or nginx and would not experience this kind of random slowdown. So more than likely this article does not apply to anybody not using google app engine.
