Have you tried whatever decent run time profiling tools that are available for your platform? A good profiler will give, for each routine: 1. Total tme spent in that routine 2. Total call count 3. Average time (from 1 and 2, obviously) A better profiler will also indicate which routines are calling a routine along with the proportions of calls by each caller. A profiler can also support code coverage determination and indicate code regions that are rarely or never executed. Profile first before writing any more code.
