Turn on the optimization of your C++ compiler ...

I think you have to explain first WHAT you want to optimize. You can optimize memory usage (usually means slower execution), execution time, access time to external ressources. Most modern compilers are using better optimization that you can hand-code. If you want to optimize the app even more, spend more time on the design of your data flow, the type of objects and the libraries you want to use.

Depending on your OS you will be able to use performance tools to find bottlenecks in your code.

In general far too much time is spent trying to optimize "code". The best approach is to proceed to completion of the project, whatever it is. Then, if optimization is needed or desired, you start by profiling the code. In terms of speed, a computer normally spends 80% of its time executing 20% of the code. With the profiler you can identify the bottlenecks, and then spend optimization effort where it is going to have some noticeable benefit.

To these comments I would add that using solid programming constructs is a good route to fast and clean code. A good programmer could write faster code in Visual Basic than a less effective programmer writing a C++ program with full optimization if the VB programmer used a smarter approach.

You will find there are dozens of areas where you could look to improve your code. Use of inlining, dynamic memory allocation, exception handling, passing arguments by reference, etc.

A widely acknowledged book on good programming practices for intermediate-advanced programming is Scott Myers: Effective C++.
