The idea here, says Google, is to avoid making Octane a micro-benchmark (like the popular SunSpider benchmark) that only tests very specific JavaScript features. In addition, Octane also runs tests based on Mozilla’s PDF reader, a open-source GameBoy emulator, a 2D physics engine and a port of the 3D Bullet Engine. The CodeLoad test also uses code derived from Closure and jQuery to measure how quickly a JavaScript engine can load and execute commonly used JavaScript libraries. Read the full details here.
