How to profile Craft CMS I would like to turn on a profiler in Craft CMS so I can see what DB queries are being run and how long they take.

Is this possible?
Yup! Just turn on devMode in your general config:

return array(
    'devMode' =&gt; true,
);


And then just open up a console (Firebug, Chrome, etc) and look in the profiling summary report.
