CodeIgniter Tip: Time Your Pages

For one of pages in the CodeIgniter application, I needed to find out how much time it takes to load. Pretty obviously first thing that came to mind was to use its built-in Benchmarking Class:

$this->benchmark->mark('code_start');

// Some code happens here

$this->benchmark->mark('code_end');

echo $this->benchmark->elapsed_time('code_start', 'code_end');

That's fine as long as you need to benchmark specific points/parts in your code.

But if you need to find out overall time page took to load, you can actually use below variable in your views:

{elapsed_time}

Or simply:

<?php echo $elapsed_time;?>

That variable is automatically created by CodeIgniter.
