Revision as of 18:12, 24 August 2011

For mobile Firefox, a very important user flow is when a user wants to quickly check a webpage from another app (e.g. email, twitter). Since Android very frequently swaps Firefox out when it is hidden, it is imperative that we start quickly. Our single-minded goal is instantaneous startup!

Basic startup stats in your console

Enable the preference: 

devtools.errorconsole.enabled

You will see something like 

[timing] main: 488ms               # When XRE_Main is called. Everything before this is 
                                   # loading libxul, static initializers, etc.
[timing] firstPaint: 1447ms        # The first paint to the screen (most important one!)
[timing] sessionRestored: 1178ms

These numbers are all measured from startup. In this example, the first paint is 1447 ms from startup, not from main.
