New Comment:
This is only the case when stat() fails.
If you change stat('.'); to stat('<some file>'); you will se that PHP5
is faster than php4. Almost 2x.

Description:
------------
filemtime and other related functions are slower on php5 vs php4
Using PHP 5.2.1 and PHP 4.4.6 on Athlon X2 3800+, Windows 2003
the speed difference is about 50-100x slower.
Reproduce code:
---------------
<?
header('Content-type: text/plain');
function microtime_float()
{
list($usec, $sec) = explode(" ", microtime());
return ((float)$usec + (float)$sec);
}
$time_start = microtime_float();
for ($i = 1; $i <= 1000; $i++) {
$blah = stat('.');
}
$time_end = microtime_float();
$time = $time_end - $time_start;
echo 'Took '.round(($time*100),3).'ms';
?>
Expected result:
----------------
Speeds should be similar
Actual result:
--------------
On PHP 4.4.6, it took about 1.6ms
On PHP 5.2.1 it took about 130ms
