Or that the CPU meter is really showing you the truth? How much of
the machine is that GUI CPU meter in the corner using, anyway?
And how do you know that C++ is not wasting those cycles?
Or that 10% is significant compared to what's being wasted by the OS?
Or that 10% is significant at all?
There are certainly some speed-critical things in the world,
but analyzing them is more subtle than most people seem to think.
Anyway, if speed of execution is the most important thing to
your application, then Lisp may not be the best choice.
Lisp performs okay (or even "well"), but speed is not
what it is optimized for.
