Why does yii2 take such a long time to generate templates?

Question

Yii

drove, means zatestit this business without caching. So the generation of data for the template takes about 0.06c. Too much of course, but tolerable. But the template with ListView and other standard widgets builds the page already 0.220c on average (for 30 news, a la blozhik). How so? They are positioning themselves as superfast?! How to speed it up? (without caching, so that it is less than 0.1c, at least 0.099)

Answer 1

They are positioning themselves as superfast?!

Every first framework positions itself this way, no one wants to be a brake.

Answer 2

To begin with, look at what the debug panel displays
How much memory it consumes, how many queries it makes to the database.
1) If the number of requests goes off scale (>> 10) check whether all related data has been connected.
For example

News::find()
    ->with([
        'author.profile',
        'category',
        'comments',
        // И остальные
    ])
    ->limit(30)
    ->all()

Thus, during a News request, all related data will be immediately received.
Instead of

SELECT * FROM author WHERE id = 1;
SELECT * FROM author WHERE id = 2;
SELECT * FROM author WHERE id = 5;

Must group all requests into one

News::find()
    ->with([...])
    ->asArray()
    ->limit(30)
    ->all()

But then you will receive all the data not in the form of an object, but in the form of an array, which will help save > 50% of the RAM.
