Hallo Christian,
16s ist aber extrem lang. Wie misst du das?
list($usec, $sec) = explode(" ", microtime());
$pr_start = (float)$usec + (float)$sec;
...
list($usec, $sec) = explode(" ", microtime());
$pr_ende = (float)$usec + (float)$sec;
$dauer = sprintf( '%.3f', round(($pr_ende - $pr_start) *1000) /1000 );
