Google, in their grasp for browser domination, have unveiled Octane, a JavaScript benchmark suite. Octane is a browser benchmark that measures performance when running the "complex and demanding web applications that users interact with daily".

Google have noted that the previous JavaScript-based benchmarks run artificial tests that were "created on an ad-hoc basis to stress a specific JavaScript feature". Where Google have steered Octane is different, as it extends the former V8 Benchmark Suite with 5 brand new benchmarks created from "full, unaltered, well-known web applications and libraries". Google have given a run down on the new tests:

• Box2DWeb runs a JavaScript port of a popular 2D physics engine that is behind many well-known simulations and web games.
• Mandreel puts a JavaScript port of the 3D Bullet Engine to the test with a twist: The original C++ source code for the engine is translated to JavaScript by Onan Games' Mandreel compiler, which is also used in countless web-based games.
• Pdf.js is based on Mozilla's PDF reader and shows how Javascript applications can replace complex native browser plug-ins. It measures how fast the browser decodes a sample PDF document.
• GB Emulator is derived from an open source emulator of a famous game console running a 3D demo.
• CodeLoad measures how quickly a JavaScript engine can bootstrap commonly used JavaScript libraries and start executing code in them. The source for this test is derived from open source libraries (Closure, jQuery).
