The web is evolving and so should the JavaScript benchmarks that measure its performance. Today, we are releasing Octane, a JavaScript benchmark suite that aims to measure a browser’s performance when running the complex and demanding web applications that users interact with daily.

Most of the existing JavaScript benchmarks run artificial tests that were created on an ad-hoc basis to stress a specific JavaScript feature. Octane breaks with this tradition and extends the former V8 Benchmark Suite with 5 new benchmarks created from full, unaltered [1], well-known web applications and libraries. A high score in the new benchmarks directly translates to better and smoother performance in similar web applications.

Here is an overview of 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). 
Besides an expanded set of benchmarks, Octane also has an interface that makes it easier to read and that adapts automatically to tablet and mobile screens.

You can try out Octane yourself, browse the source code, or read more about each benchmark at the Octane site. Still have some questions? Have a look at the FAQ page.
