The way files are included can be a significant performance issue.

It's best to use full, true, paths when including files.  One strategy
I've used is having all scripts include one central config file via a
relative path.  Then in that script do this:

define('PATH_BASE', realpath(dirname(__FILE__));

Then all other includes/requires in the application should do:

require PATH_BASE . '/subdir/whatever/some_other_file.php'

This removes the need to use the include_path and simplifies the
operations PHP needs to do for caching file names and paths.

Also, carefully consider the order of entries in the include_path
setting.  Put the directories in there in order of most used first,
least used last.
