Profiling

I would like to find the loading bottlenecks of my app.

When I look at the profiling too in the yii debug bar I see the AWESOME query profiler… this helps alot…

However to load my page, (1400 ms) the database take 84ms

What is the easiest way to see where the other time is going ?

(I could install xdebug, but I wonder if there is a more integrated and easier way in yii)

The best way is Blackfire or XHProf (there are some modern forks as far as I remember) but if you prefer Yii debug toolbar you can add profile calls to your code. Check the guide on performance.
