Make a directory called test, go in there and put this version of the script in there:

<?php

/*

Experimental NFS detector - upload this file to server and chmod 777

Script should take less than one second to run.

If it takes more than one second, then it's likely NFS (or Windows or a bad configuration)

Any error means the time is unreliable as the script has failed.

*/

error_reporting(E_ALL);

$file=dirname(__FILE__)."/test.txt"; file_put_contents($file,'');

$time=strtok(microtime(),' ')+strtok('');

for ($i=0; $i<=9999; $i++) {if (touch($file)) {clearstatcache(); filemtime($file);} else {break;}}

echo ((strtok(microtime(),' ')+strtok(''))-$time)." seconds";

?>
