1203464 - [Messages][Performance] Consider delaying of expensive gaia-header initialization for the secondary views

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia::SMS, defect, P3)

Description

[Oleg Zasypkin [:azasypkin]]

From profiles in bug 1198266, we see that initialization of gaia-header can be quite expensive (~20ms for every gaia-header on Flame-KK). For non-split views we initialize 6 gaia-headers while only one is really needed to be displayed as soon as possible. It also seems that we remove "no-font-fit" from secondary edit mode gaia-header too early: in InboxView.beforeEnter and ConversationView.beforeEnter.

So I this bug we want to try the following things:

* Add/initialize secondary gaia-headers only when needed or at least when "visuallyLoaded" is fired;

* Delay removing of "no-font-fit" for the edit mode header.

In the scope of bug 1211395, Steve fixed "edit" gaia-headers issues, so the only thing we want to consider here is to lazily insert gaia-headers to the DOM for the following cases to spend less time on gaia-header web component initialization: edit headers and headers for Report and Group views.

However we need to retake profiles first to see if it still can be significant issue + this also can be "automatically" fixed once we split these views.

Mass closing of Gaia::SMS bugs. End of an era :(
