Comment #6 on issue 1630 by [email protected]: Compiled raytrace code is very slow
http://code.google.com/p/v8/issues/detail?id=1630
From the profile it looks as if a lot of time is spent in slow-case property-stores. (v8::internal::Runtime::SetObjectProperty and the function it calls. It seems some array or object is in dictionary mode (v8::internal::JSObject::SetDictionaryElement)
