Great tech article from Sencha on mobile web app performance

New mobile apps are compute intensive: no-one is trying to do DNA sequencing on an iPhone. Most apps have a very reasonable response model. The user does something, then the app responds visually with immediacy at 30 frames per second or more, and completes a task in a few hundred milliseconds. As long as an app meets this user goal, it doesn’t matter how big an abstraction layer it has to go through to get to silicon. This is one of the red herrings we’d like to cook and eat.
