Why is DESCRIBE query called and is there a way to reduce it?

Hey guys!

So I am trying to understand my performance.

I have a application built on INVO, phalcon 3.4.7. Empty controller, only in BaseController I call a user object.

Thing is DESCRIBE QUERY is called, even when the object is cached. And it is a majority of my loading time. I dont understand why. Whats the point of cache if 90% of the load (Describe) is still called? My understand is DESCRIBE is called because I call a user object. Can I optimize this in some way?

<?php

use Phalcon\Mvc\Controller;
use Phalcon\Mvc\View;
use Phalcon\Cache\Backend\File as BackFile;
use Phalcon\Cache\Frontend\Data as FrontData;

class ControllerBase extends Controller {

    public $user;

    protected function initialize() {
