Slow modules in Yii?

Question

Yii

Used framework: Yii (oddly enough)).
Faced a problem: slow modules. Moreover, from profiling it is not clear which of them is slow. There are queries to the database, but they are not as slow as the total page load (2 seconds). I would like to reduce to 1 sec. or at least closer to that number.
So here's the picture.
From the log, we see that after enabling the session component, it immediately goes +2 seconds. Disabling the isGuest() check in right.php (everything is visible there) does not increase anything. Then immediately the next request, after the previous one, starts loading after 2 seconds. Profiling queries to the database gave the following result: the picture is here .
Tried on 2 variants of iron: the result is the same.

Answer 1

Profile with a normal tool like XDebug, log a normal (non-slow) page and a slow page for comparison, and compare. Modules can put their hooks on different events. It is difficult to say anything from the given data. Requests to the DB, apparently, have nothing to do with it.

Answer 2

How is your session stored? Something took an indecently long time to initialize.

Answer 3

and who has the speed of Yii without a database and APC? so let's say cleanly output Hello Word
