Subject [jira] [Commented] (CB-2232) Initial app launch is 10x slower than subsequent ones on a device
Date Thu, 17 Jan 2013 07:04:12 GMT


Shazron Abdullah commented on CB-2232:

I forgot to disable backgrounding - so in the StartupBench-Info.plist file, add "Application
does not run in background" to "YES". This is so when you press the Home button, it kills
the app so you can run an iteration again.

The app is based on the tip of tree 2.4.0 edge code as of this writing.
> Note that this project the splashscreens from the Resources group have been removed,
as well as the icons and splashscreens in www/res.
> Initial tests reveal that yes, the initial startup time is slow (probably because of
the resource copying), but it is never 10x.
> I have attached a screenshot of the results screen as well.
