Don't have a Windows machine readily available or I would try this out.
The OP would have done well to try commenting out the entire body of foreach to see if
something in the body was slow, or whether it was just the process of iterating through the
directories and files.

Description:
------------
On Linux it is really easy to read recursive folder-listings with SPL even if there are many files
and folders, i need here between 1 and 3 seconds after cold start of the machine on my fedora-box
On Windows the same needs between 180 and 240 seconds and "process explorer" shows > 1
MB I/O the whole time, same script, same folders contents, same php-version
WHAT do you do on windows?
Are you reading all the 30.000 files instead listing them only?
Test script:
---------------
<?php
$files = array();
$folders = array();
$spl_objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path),
RecursiveIteratorIterator::CHILD_FIRST);
try
{
foreach($spl_objects as $filename=>$spl_object)
{
if(DIRECTORY_SEPARATOR === "\\")
{
$filename = str_replace(DIRECTORY_SEPARATOR, '/', $filename);
}
if(substr($filename, 0, 2) === './')
{
$filename = substr($filename, 2);
}
switch($spl_object->isDir())
{
case false: $files[$filename] = $spl_object->getMTime(); break;
case true: $folders[] = $filename; break;
}
}
}
catch(UnexpectedValueException $e)
{
error_log('Directory "' . $path . '" contained a directory we can not
recurse into');
return false;
}
sort($folders);
ksort($files);
$enumerate_list = array('files'=>$files, 'folders'=>$folders);
unset($folders);
unset($files);
?>
Expected result:
----------------
a normal performance
Actual result:
--------------
waiting minutes to get hughe folder-listings
