Only under some circumstances.  For example, a 100-iteration
calculation loop with a large constant subexpression would be almost
100 times faster under release than under debug.  In the case you're
referring to, LLPointer<LLViewerPart>::operator=(LLPointer<LLViewerPart>
const&) is a smart-pointer assignment operator.  In the release build,
this function won't even exist: it'll be converted into two inline
statements: an assignment and an increment.  Without the function-call
overhead, it'll run about 50-75 times faster.
