I didn't think that this was much of a thing that needed to be investigated. Adding additional processing into your code will make it slow down.

On a related note, I had a consultant come into my work one time to the teach us some pragmatic things in C++. One of the lessons was that that gcc will not attempt to reorder the code within a try block to optimize it. This could be leading to some very minute slowdown in a C++ app in addition to the overhead associated with try/catch as a whole
