My Programming Perl book says that profiling results should be forgiven some inaccuracies, but these numbers don't even seem close. Can somebody explain that top function below to me? An average call time of 0.0002 times 175353 calls doesn't get anywhere near 4000 seconds the way I do math. What am I not getting here?
