I hardly believe strings can affect performance seriously. They are typically not used for objects in deep layers. Or may be there are mentioned cases of unintentional behavior? Can you provide most striking example? What about making ctors explicit - this needs definition of non-trivial ctor. ------------------------------------------------------------------------------ What NetFlow Analyzer can do for you?
