Caching always loading files in PHP

In my index.php file I always load some classes used later. From profiler it states it sometimes can take about 20% of entire code. Is there any improvement that can make this process faster?

I would try to make this list of classes shorter, but app is very big and checking all dependencies will be costly.

While using an opcode cache (such as APC) will reduce the impact of loading/parsing/compiling the class, you'll still be loading them all on every page load & doing whatever initialization accompanies a require_once() call. If you were to set up an autoload function then the classes won't be loaded until your code actually needs to use them. There's a little overhead involved in using a class autoloader but it makes the code easier to maintain.

As always, YMMV, so benchmark your application to see if it's worthwhile in your case.

Op-code caches such as APC and eAccelerator store a compiled version of your scripts in a cache. This dramatically reduces memory usage and loading time for frequently used static scripts.
