The approach to decrease loadtime: * check index.html to find out possible redundant or removable piece. (done) * check startup js to remove unnecessary code in startup Current diagnoses (and tasks that align with existing development goal): * remove USB switch/warning dialog in root panel (2.5) - due to UX change (will reduce size of loading) * remove BT APIv1 support (maybe after 2.5) - remove BT detection code and remove BT helper dependency (will reduce size of loading) * convert rest of pack-switch css to gaia-switch (will clean some css) I'd expect ~100ms improvement with above change. Need dig into js startup procedure to squash more improvement space.

According to Current state of performance in Gaia 2015/10/2 Settings v2.2 cold launch: 2474ms Settings current cold launch: 2950ms (~475ms regression) Settings v2.2 USS: 17.18MB Settings current USS: 17.54MB (acceptable)
We'll also check with raptor tool to see if make html import on demend (only load needed html/js) will save some loadtime.

According to test result, remove BTv1 API does not save loadtime
