PhantomJS 1.6+ is required to run loadreport.js or speedreport.js.
phantomjs speed-daemon.js <format> <url>
<format>is optional and specifies what should be written ('html' or 'json')urlis the URL to be analyzed.
In addition, the following parameters may be specified...
-config <config-file>specifies an external config file to be used-out <out-file>specifies the base name of the output file to be written (i.e., 'my-report'). If not specified, defaults to a modified version of the url.-ua <user-agent>specifies the user agent to use. Supported user agents include 'firefox', 'safari', 'chrome', iphone', and 'android'.
The speed-daemon script started life as James Pearce' Confess, and was then modified by Wesley Hales who added the speedreport.js magic. This fork is focussed on using speedreport.js as part of a larger process of gathering metrics on web pages.
