Principles of Code Optimizations Using
Profiling Tools
• Timing data in the profiler report in Simulator is not the
same as that of the phone. Sometimes they are not even
proportional.
• Profiling report by PC tools (e.g. GlowCode) is still helpful
in shedding light into the behavior of you module on target.
– The time spent in a function and its children. This lets you
follow the “hot path”—the series of function calls responsible
for the majority of the execution time.
– The number of hits in a given function. Function with higher hits
could be part of the “inner loop”, and should be looked at with
more carefully.
