include() really slow (by ~2 seconds)

[societyofrobots]

For some reason, include("my_file.php") takes ~2 seconds. If I include the exact same code that's in that include file outside of the include() it works fast, no problem.

 

I've tried turning on php output_buffering=on and using file_exists() but no luck. I even tried:

include($_SERVER['DOCUMENT_ROOT'​​] . '/my_file.php');

but the delay was the same.

 

Ideas? I'm using PHP Version 4.3.9.
