Not when you're talking about the kind of optimizations we did where we tried to spare every Assembly code possible (and I'm sure there will be some more such passes when things settle down). If you'd write Zend in the correct OOP way you'd have a lot of virtual functions and stuff like that which would actually be slower than the way it is written now. Of course, you could write C++ in a C'ish way but then you wouldn't gain much. I like C++ a lot, and I find OOP design very interesting, but if you design well in C++ vs. C you'll definitely be faster in C. However, doing a good design in C is much harder than in C++ IMO. And OOP design is quite a difficult subject itself. Andi
