Speedometer is a browser benchmark that measures the responsiveness of Web applications.
|
||
It uses demo web applications to simulate user actions such as adding to-do items.

<h1>About Speedometer</h1>
|
||
|
||
<p>Speedometer measures simulated user interactions in web applications.</p>
|
||
|
||
<p>
|
||
The current benchmark uses TodoMVC to simulate user actions for adding, completing, and removing to-do items.
|
||
Speedometer repeats the same actions using DOM APIs —
|
||
a core set of web platform APIs used extensively in web applications —
|
||
as well as six popular JavaScript frameworks: Ember.js, Backbone.js, jQuery, AngularJS, React, and Flight.
|
||
Many of these frameworks are used on the most popular websites in the world, such as Facebook and Twitter.
|
||
The performance of these types of operations depends on the speed of the DOM APIs, the JavaScript engine,
|
||
CSS style resolution, layout, and other technologies.
|
||
</p>
|
||
|
||
<p>
|
||
Although user-driven actions like mouse movements and keyboard input cannot be accurately emulated in JavaScript,
|
||
Speedometer does its best to faithfully replay a typical workload within the demo applications.
|
||
To make the run time long enough to measure with the limited precision,
|
||
we synchronously execute a large number of the operations, such as adding one hundred to-do items.
|
||
</p>
|
||
|
||
<p>
|
||
Some browser engines use an optimization strategy of doing some work asynchronously to reduce the run time of synchronous operations.
|
||
While returning control back to JavaScript execution as soon as possible is worth pursuing,
|
||
a holistic, accurate measurement of web application performance involves measuring
|
||
when these related, asynchronous computations actually complete.
|
||
Thus, Speedometer measures the time browser spends executing those asynchronous tasks in Speedometer,
|
||
estimated as the time between when a zero-second delay timer is scheduled and when it is fired.</p>
|
||
|
||
<p class="note">
|
||
<strong>Note:</strong> Speedometer is not meant to compare the performance of different JavaScript frameworks.
|
||
The mechanism we use to simulate user actions is different for each framework,
|
||
and we’re forcing frameworks to do more work synchronously than needed in some cases to ensure run time can be measured.
