Bruno shows some causes of slow web scripts and gives possible solutions.

This article shows you how PHP cache mechanisms work and provides a do-it-yourself solution. If you test the examples and like them, please feel free to implement your own solutions. However, there other ways to improve performance like function caching, or PHP script precompilation. Some off-the-shelf solutions can offer you these functionalities. You should always look for the best solution for your own needs and do your own testing.
