854811 - [System][Performance measurement] Show activity launch time

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Gaia::System, defect)

Description

[(inactive after 6/18) Alive Kuo [:alive]]

Currently we only display the load time of app by ttl_view module in system app.
However, open inline activity is also another way to load an individual page from an app(normally.), also may consume plenty of time if it's not fine-tined.

I am making a patch to show activitiyloadtime on ttl_view.

Note:
I don't know how datazilla is integrated with apploadtime event, try to study.

Etienne, could you please review this change?

The changes sounds OK to me. I tend to think that some performance tests can be written for a specific activity using the framework we have in Gaia. Anthony and Julien can you help setting up some of those tests or helping alive to write some so they appear in http://datazilla.mozilla.org/b2g/ ?
