A suite of tests for EmberJS to help with performance

Ember Performance Suite

The Ember Performance Suite is designed to help profile and diagnose the performance of the Ember.js framework. The general strategy is:

• Browsers have a large variance in performance characteristics, so run each test in a new document, storing the results in localStorage.

• Use benchmark.js for micro benchmarks and a different strategy for macro benchmarks.

• Record Baseline performance so that we can compare Ember to the baseline performance of the platform it's run on.

Is your custom build crashing Safari during rendering tests?

There is a known bug with Safari and use strict. Some versions of Ember (1.8.1 and greater) have stripped out use strict to prevent it. Unfortunately, that fix causes the Ember performance suite to crash after running repeatedly.

In particular the lack of use strict shortly after defining ember-metal/mixin causes the crash. It has been added back in the builds of ember that ship with the performance suite, but you might encounter it if you are using a custom build.

To run in development mode

1. npm install
2. bower install
3. broccoli serve

And open a browser to http://localhost:4200

To build for production mode

1. npm install
2. bower install
3. brocolli build dist

The compiled version will be in your dist folder

To add a new test

Create a new directory under tests, for example tests/my-test and define an index.js file that calls TestClient.run.

Example:

TestClient.run({
  name: 'Ember.Object.create',
  microBench: true,

  test: function() {
    TestClient.PEOPLE_JSON.forEach(function(p) {
      Ember.Object.create(p);
    });
  }
});

(Please see the other tests for more examples.)

After you've created the test, add it to the manifest of tests in app/app.js
