Application profiling :
Profiling your application is disabled by default. You can configure Fuel to activate the profiler via your applications config/config.php file.
'profiling' => true,​
After the profiler has been enabled, you will see it pop up at the bottom of your browser window.
Database profiling :
Database profiling is disabled by default too. Database profiling is activated per defined database, and is activated by setting the 'profiling' option of the database configuration you want to profile in your config/<environment>/db.php to true.
