Summary Document::styleRecalc() and FrameView::layout() should be traced
Kentaro Hara
Reported 2013-02-22 14:18:50 PST
Document::styleRecalc() and FrameView::layout() are key factors for web page rendering performance. We should add TRACE_EVENT() macros to these functions.

I found that style recalculation and layout have not been traced... With the patch, we can observe style recalculations and layouts inside v8.run and v8.callFunction. (That being said, style recalculations and layouts explain a small part of v8.run and v8.callFunction when we open a Google Docs.)
