 ==== Optimize your data ====
-Usually the most expensive places of the PHP application are where it accesses external data – namely, database or filesystem or network. Look hard into optimizing that – reduce number of queries, improve database structure, reduce filesystem accesses, try to bundle data to make one service call instead of several, etc. For more advanced in-depth look, use tools like strace (Unix) and Process Explorer (Windows) to look into system calls your script produces and think about ways to eliminate some of  them. You would not be able to eliminate all of them but each of them is a worthy target.
