Oh I see. So low end devices in india which are predominantly android smart phones do not have the capacity to cache 500kb of frequently used JS?

Reducing the overall page size of a given page doesn't help

Optimizing rendering for content first and images loaded as required doesn't help

Serving pages from a super fast global CDN doesn't help

And prefetching content behind the scenes also doesn't help

I think you should take these to Google because it seems like they've totally goofed this AMP thing!
