Create 2 PHP files to compare difference. I like it!
– simple.php
<?php
    set_time_limit(0);
    for ($i = 0; $i < 100000; $i++) {
        echo “$i. This is line $i <br>”;
        sleep(2);
    }
?>
– buffer.php
<?php
    set_time_limit(0);
    for ($i = 0; $i < 100000; $i++) {
        ob_flush();
        echo “$i. This is line $i <br>”;
        sleep(2);
    }
?>
