Well, frankly id say that this is the last advice to give. Much better is a period of reflection and analysis, followed by some research. Then you put together a system using sound algorithms. Then finally, when you need to cream some extra speed out of the system, then you do profiling.

The point is that if you are using Bubble Sort to reorder a million record file in random order you can profile it all you want without ever making it go as fast as a mergesort would have.

IOW: think first, then profile.
