It seems that the problem is related to several file-related functions.
I have personally experienced this also with the is_dir function.

Description:
------------
file_exists, include, include_once, require, require_once and
getimagesize are about 10x slower than their php4 version.
Using Apache 2.0.48, Windows XP
Php 5.0.0 versus Php 4.3.6 on the same computer.
Reproduce code:
---------------
Tested using this function either with file_exists, include,
include_once, require, require_once and getimagesize
function FileExists($file,$nb,$para="")
{
$aT=array();
$aT[0]=microtime(false);
for($t=0;$t<$nb;$t++){
file_exists($file);
}
$aT[1]=microtime(false);
return $aT;
}
Actual result:
--------------
