Thank you Jacob! Seeing it take 22% is rare. Is your app heavy on polymorphic property loads? Yes, I'm writing an interpreter and it was doing a *lot* of instanceof checks. Since I don't have undefined or null values in my interpreter, rather than use x instanceof Foo I can instead give Foo instances a "type" property of e.g. 100 and use x.type === 100, which is faster. So indeed yes, now it's doing a lot of polymorphic property loads! :-) Makes perfect sense, thanks! -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
