Make sure your optimization settings are set to max. The difference between optimized and unoptimized C++ code can be huge. In general, if your code doesnt run as fast as C code, your code is crap. Forget the "10%-overhead is ok" or "templates are slow" shit. Its wrong. C++ does what C does and goes miles beyond. If your perl-code is faster than your c++ code youd probably refrain from posting on./ and do a little more coding work.
