- WARNING!!!
- The goal in using a profiler is to best direct your efforts in improving program
performance.
- Alway keep Amdahl's Law in mind when optimizing.
Amdahl's Law (Simple Version):
If N% of the program's time is spent in method X, the maximum performance
improvement obtainable from optimizing method X is N%.
|
Don't Make This Mistake: |
Many people ignore Amdahl's Law and do one of the following:
- They optimize things they know how to optimize, even if they are rarely used.
- They optimize things they know are called frequently, even if they don't drive the
program's performance.
While optimization is always a good idea, optimizing the wrong things will have a negligible
effect on the program's performance.
