--- Comment #2 from zalan <zalan at apple.com> ---
While loading the page we spend significant amount of time in 
pumpTokenizer (28%) -> SegmentedString::operator= (25%)
and WTF::Deque<SegmentedSubString>::destroyAll (11%)
Also Style::resolveTree() (11%)
After finished loading another round of style resolving kicks in with Style::resolve(37.2%) -> getUncachedPseudoStyle(13%)
While scrolling, we spend most of the time in cell painting -> text drawing.
