Yii2 - why does View::render() slow down?

Question

Yii

Goodnight. Tell me please. Requests to the database take 9ms in total, and rendering of even the simplest view takes 200ms. XDebug turned off, what could be the problem? I am using Yii2. The problem is not in the framework most likely

You won't regret using xhprof
And first, see if you have columns in the GridView in html format

GridView::widget([
    'dataProvider' => $dataProvider,
    'columns' => [
        'title:html',
        'description:html',
    ]
])

If you use the html format, then the displayed text will be filtered using HtmlPurifier, which is a very tormented library.
