How many threads and SMS do you have in your measurements ?

On Keon this takes 600ms.

Will it help to attach the SMS DB with the test data?

Yes please, it will help a lot working on the same data set :)

Per Sandip in bug 914910: First time launch latency goal for SMS app is 1200ms.

Julien - this is a CS blocker brought up by QC, are you getting any progress in investigating the regression and/or driving down the launch latency in v1.2 with a forward fix?

I've not investigated much yet, and at least not with the provided attachment yet.

Something planned for this week.

What do I do exactly with that .zip. If I adb push its content to replace /data/local on my device, I don't even get b2g to restart.

I get the following error messages in logcat

E/GeckoConsole(  866): [JavaScript Error: "DOMApplicationRegistry: Could not parse JSON: /data/local/webapps/webapps.json [Exception...

These are the steps I followed:
1) Download and extract attached zip file
2) run |adb root|
3) run |adb remount|
4) run |adb push local /data/local| 

Also, you can try rebooting the phone.

It works for me.

I only pushed the sms databases.

Could not get a working 1.2 buri yet.

[Julien Wajsberg [:julienw] (PTO -> Aug 24)]

So, I get around 650ms on 1.1 for the first paint, plus around 500ms for showing the first message.

Aaaaaaaand. the same for 1.2.

Both on Buri.
