You can always see the "Loading time:..." in many web sites
Well this is a simple way on how to do it: 

<?php 
// Get Current Time 
$mtime = microtime(); 
// Split Seconds and Microseconds 
$mtime = explode (" ", $mtime); 
// Create a single value for start time 
$mtime = $mtime[1] + $mtime[0]; 
// Write Start Time Into A Variable 
$tstart = $mtime; 

// Get current time (Like above) to get end time 
$mtime = microtime(); 
$mtime = explode (" ", $mtime); 
$mtime = $mtime[1] + $mtime[0]; 
// Store end time in a variable 
$tend = $mtime; 
// Calculate Difference 
$totaltime = ($tend - $tstart); 
// Output the result 
printf ("This page was generated in %f seconds.", $totaltime); 
?>
