774397 - Tweak content sink settings to improve responsiveness during page load

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Jonathan Wilde [:jwilde]]

Switching content.sink.enable_perf_mode to 1 (interactive mode) makes the UI really responsive, but isn't ideal from a page loading time standpoint.  I'd like to keep it on 0, the Firefox desktop default.  However, the process of loading content.js into tabs is enough to still cause the UI to hang a bit.

There's some tweaking of the content.sink settings needed to find a balance between page loading performance and UI responsiveness during page load.

content.js is only a few lines of script, seems odd that it would hang the browser. Regardless, maybe there is some way to move that functionality out of tabs and not load it at all?

I've been tinkering with this lately, and the browser is pretty responsive.  I'm guessing that the lag that we were having might have been due to some other front-end issue rather than content sink settings.

Given that we want to keep the performance settings as close to desktop fx as possible (unless there's a really good reason to do otherwise), I think we should just tag this bug as resolved/worksforme.
