That's not really true: all the profiling code does is to hook the timer tick interrupt and run a 5-line C function when the timer ticks. For 18 times a second, this is nowhere near a performance hit. One other thing that profiling does is to call another function each time the application calls one of its functions (not the library functions). I don't think this should mean a performance hit, either, unless the application has lots of small functions which are called a lot.
