meta bug for tracking view positioning optimizations
Blocks: 71668
Status: NEW → ASSIGNED
Depends on: 97934, 100585, 100590

I ran jrgm's tests on  build where the bodies of
nsContainerFrame::PositionFrameView() and nsContainerFrame::PositionChildViews()
were #if 0'd out. That build was about 4% faster than the normal build. So it
looks like view optimization might be worth investigating further.

Normal Build:

Test id: 3BC2786352
Avg. Median : 917 msec		Minimum     : 250 msec
Average     : 993 msec		Maximum     : 3526 msec

Without nsContainerFrame view positioning routines:

Test id: 3BC280185E
Avg. Median : 881 msec		Minimum     : 251 msec
Average     : 951 msec		Maximum     : 3406 msec
