Blink's Rendering Pipeline

Anyone here targeting HTML5 mobile apps? I have been digging through some WebView stuff lately and I find the results surprising.

The rendering pipeline is complex and layout code consumes a lot of CPU. The end result is that HTML5 mobile apps are slow and consume more CPU. I have also tested with the chromium beta channel. Things have improved vastly but it's no where close to native code. If you take some advanced 3d games, they consume like 20% CPU on latest Nexus. Just do some simple 2d animations in Chrome using canvas and you are already at 30% (so this doesn't even count physics and all that).

Blink is the rendering engine used by Chromium.
