I notice that the dev server takes 700ms to serve app.js. Of this 200ms is “waiting” and 400ms is “content download”. I wonder why that is? Shouldn’t it be a quick local retrieval taking a few hundred milliseconds at the most?
Also, for testing purposes, I want to set app.js (and other static assets) to be cacheable. Right now, it is served with a header of max-age=0. Where/how can I change the cache settings for files served by the dev server?
