Disclosure: I also work at Ionic

So start up time is something that we are very focused on at the moment. Especially on the PWA side of things, TTI (time to interactive) is exceedingly important to ensure a good user experience. We are working on a few things at the moment but most likely the first one to hit is gonna be code splitting. So with code splitting, instead of shipping just one big bundle you will be shipping smaller bundles that are lazy loaded based on routes. This means that when the app first loads only the first bundle for the first view in your app will have to be loaded, parsed etc and then the other bundles will be lazy loaded. With this setup the browser (or webview) will never have to parse and load a huge bundle all in once, it will instead only have to deal with smaller bundles. This should give a pretty big improvement as parsing javascript is slow in every browser. From my testing on a moto g each MB of JavaScript in an ideal situation takes about 2 seconds to be parsed, so reducing the amount of JavaScript the browser has to deal with is a very fast way to get better load times.

Well, these are good news. Any timeline to expect the results from this to be suitable to apply in production?
