Can anybody point me to code that gets run when accessing a property on a DOM node in OSS rendering engines?
In general, for Gecko a prop get that does an actual vmcall will be about 20-30 machine instructions plus the C++ getter cost.

Where C++ getter cost is not including the binding layer. For .firstChild C++ getter cost is a single mov, of course.

Oh, and if the get result needs a new reflector or is a string that will of course cost a bit more....
