1108955 - Improve the speed of build_stage

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Gaia::Build, defect)

Description

[Ricky Chien [:rickychien] (inactive)]

We should figure out whether build_stage is a necessary step for build process or speed up in another way.

It takes between 1 and 6s to rebuild an app with `APP=foo make`.
It is too much. It should be faster, especially in developer mode, without all optimization (minification, compression, multilocale, ...).

I was able to save 1s of build time with this naive optimization in multilocale optimize step...
But I think we could win even more with better data structure or some better algorithm to do this!

So the system app now takes 2s to build instead of 3s.

Also I looked at why clock is taking 2s to build, most of this time is spent in r.js and it is not really clear what we do here and what precise code is taking almost a second to process this simple app.

For-loop caching ftw!  Thanks :)  r=me with a suggestion left on github.
