Comment #3 on issue 32040 by jam...@chromium.org: Amount of HTML on a page
seems to affect script load+parse time
http://code.google.com/p/chromium/issues/detail?id=32040
Most of the time is going into WebCore::HTMLNameCollection::itemAfter(),
according to
pprof. This is a linear walk through all elements in the DOM which is
checking if
any match a given 'name' parameter. It's invoked via;
http://trac.webkit.org/browser/trunk/WebCore/bindings/v8/custom/V8DOMWindowCustom.cpp
#L812
which is called through some intermediates by:
http://code.google.com/p/v8/source/browse/trunk/src/runtime.cc#689
whenever globals are set up. So basically, doing a linear walk and
comparison on
every DOM node for every single global variable in the script. Mike, Mads
- what's
going on here? This looks not good.
