title: Is there a need to use various peformance optimization techniques when using html5 appcache?
body: <p>I have an Angular/Firebase/Mongo webapp. Designed to be downloaded to home page and run as a "local" app. My question is if I am already caching the files normally requested from the server via the html5 appcache, do I need to concat, minify and use techniques like template caching?  All of these techniques are all designed to minimize the amount and frequency of server calls.  Since the app is getting these locally, is there still a benefit to these optimizations? </p>
