I know that adding ' to keys like 'post_title' makes it 7-10 times faster, so it's very good practice to do that

Only way I can think of testing is using time() when the script begins and ends (maybe repeat commands to make noticeable times) so you can see how many milliseconds it took.

Here's the way I tested it. It uses microtime, since time would not actually do anything

PHP Code:

$mtime = microtime();
$mtime = explode(" ",$mtime);
$mtime = $mtime[1] + $mtime[0];
$starttime = $mtime;
//////////////////////////////////////////////////////////////////////////////////////////////////////////
$i=0;
$j='';
$k=array('Test','Script');

for($i=0;$i<50000;$i++)
    $j=$k[1];#DELETE AS APPROPRIATE
    #$j=$k['1'];#UNCOMMENT AS APPROPRIATE

//////////////////////////////////////////////////////////////////////////////////////////////////////////
$mtime = microtime();
$mtime = explode(" ",$mtime);
$mtime = $mtime[1] + $mtime[0];
$endtime = $mtime;
$totaltime = ($endtime - $starttime);
echo "This page was created in ".$totaltime." seconds"; 

Make sure you have only the first or the second line after the for loop
EDIT: Also, try it about 5 or 6 times minimum, to get a fair average
