How to reduce memory consumption in Yii2?

Question

Yii

I am writing a website on this framework and I am confused by the memory consumption of 8 meters per page with 15 requests to the database (it will not work to make one). At a time when a self-written framework that does everything I need, hawala a little more than 1.5 meters. My bike does not have active records like in Yii2. What do I need to disable in Yii2 so that I can upload the site to the host and not think that it will be cut down nah? logs and debugger are disabled.

Answer 1

Optimize queries in the database, enable the query cache in the config.
Optimization and only optimization.
My site can have over 1000 requests on a single page with 18mb memory consumption and 150ms load speed;
My settings are something like this:

'components' => [
     'db' => [
    'enableSchemaCache' => true,
          'schemaCacheDuration' => 3600,
          'schemaCache' => 'cache',
     ],

     'cache' => [
          'class' => 'yii\caching\MemCache'
     ],

]

Just enabling caching is not enough, you need to correctly scatter it in the views of everyone, so that not everything is cached in a row, this is dangerous for dynamic blocks. There is a lot of information on the Internet about this.
Minification and concatenation of all JS and CSS files also greatly reduces the load. yii2 has both built-in tools for this, as well as additional modules, such as rmrevin.
