It appears in all tests and for first and second visits though local-blank has a clearer signal. It also appears later on mozilla-central and mozilla-inbound as the merges occur.

Looks like Bug 1252666 - Flip dom.push.enabled to true in Firefox for Android

It looks like enabling push notifications regressed page load time.

Jim, can you look into this?

(Edwin, I wanted to make sure this is on the push team's radar.)

Delay initialization of PushService and DLC in GeckoApplication to after
the Gecko:Ready message. That way, hopefully they give up some CPU time
to other initialization tasks.

Delay initializing PushService and DLC (v1)

Approval Request Comment
[Feature/regressing bug #]: Push
[User impact if declined]: Slower startup time due to push being enabled
[Describe test coverage new/current, TreeHerder]: Locally, m-c
[Risks and why]: There is one known regression (bug 1280446), which will be uplifted; otherwise the risk is small because the patch simply delays push initialization on startup
[String/UUID change made/needed]: None

This patch fixes slower startup time. Take it in 48 beta 7. The fix should be in fennec 48 beta 8.
