Basic benchmarks to measure HTML5 performance and support for game related features

Running the Tests

  1. Install Node.js (0.6.0+).
  2. Run in shell: npm install
  3. Run in shell: node server
  4. Open in browser: http://localhost:3002/
  5. Configure parameters of the test run, if desired.
  6. Click "Run Tests".
  7. If you uploaded results, see the server/uploads/ directory.

Interpreting Results

Sprite tests

The Source type indicates the data being displayed.

The Technique indicates the browser method used to render the data.

The Test type indicates what transformations were performed on the data using the technique.

The JS time (ms) result shows how much JavaScript time was spent rendering the objects in one second.

The Objects at 30FPS result shows how many objects were able to be rendered while rendering at 30 frames per second.

Audio latency test

The Cold play latency indicates how much time it took between .play() and the first subsequent play or timeupdate event on a new WAV <audio> element.

The Warm play latency indicates how much time it took between .play() and the first subsequent play or timeupdate event on a WAV <audio> element which has already played.

Canvas text test

The Score result shows how many renders could be made per 100 milliseconds.

Code structure

Test cases are build into a recursive object structure. Test cases are run through the test runner in js/testRunner.js.

Test cases are displayed based upon the specification in js/tables.js.

Sprite tests

Sprite tests are found under js/sprites/.

There are three interleaved components:

Sources

Each source represents some asset (e.g. a sprite sheet). Maps to the Source type result.

Transformers

Transformers modify the source by applying affine or other transformations. Maps to the Test type result.

Renderers

Renderers displayed transformed sources using different techniques. Maps to the Technique result. See js/sprites/renderers/README.md for details.
