I see they have measured improvements in the performance of some things. In particular, the camera app starts faster. Small percentage, but still real.

Curious if there are any other changes you could do based on some of those learnings? The camera app, in particular, seems like a good one to optimize to start instantly. Especially so with the the shortcut "double power key" that many phones/people have setup.

Specifically, I would expect you should be able to do something like the lisp norm of "dump image?" Startup should then largely be loading the image, not executing much if any initialization code? (Honestly, I mostly assume this already happens?)



A big part of the challenge for launching the camera app is getting the hardware ready and quickly freeing up RAM for image processing.


Makes sense. That it is so much faster on repeat wakeups does seem to hint that it could be computing a something. I'm assuming you are saying that most of what is getting computed is related to paging in/out memory? That would track on how it could be better with larger pages.
