Yii2 redirects through apache, improving performance by 10 times

This test code is based on yii2 framework, apache server, apache, mysql, memcache are all installed on the same machine.
The test business content displays a list of articles, as shown below:

Test 1. Direct database access mode, test code.

class ListController extends Controller
{
    public $layout = false;
    public function actionDb()
    {
        $specialRecommend = new SpecialRecommend();
        $page = empty($_GET['page']) == false ? intval($_GET['page']) : 1;
        $pageSize = 10;
        $rows = $specialRecommend->find()->offset(($page - 1) * $pageSize)->limit($pageSize)->orderBy("sid desc")->asArray()->all();
        $html = $this->render('index', [
            'rows' => $rows,
        ]);
        return $html;
    }
}

Test 2. Add the cache and test the code

public function actionCache()
{
    $page = empty($_GET['page']) == false ? intval($_GET['page']) : 1;
    $pageSize = 10;
     $key = "cacke_key";
        $data = Yii::$app->cache->get($key);
        $rows = json_decode($data, true);
        if(empty($rows) == true){
            $specialRecommend = new SpecialRecommend();
            $rows = $specialRecommend->find()->offset(($page - 1) * $pageSize)->limit($pageSize)->orderBy("sid desc")->asArray()->all();
            Yii::$app->cache->set($key, json_encode($rows));
        }
        $html = $this->render('index', [
            'rows' => $rows,
        ]);
        return $html;
}

Test 3. Turn on yii2 pseudo-static. When setting apache redirection, first determine whether the directory exists. If it exists, directly access the real directory
.htaccess

Options +FollowSymLinks
    IndexIgnore */*
    RewriteEngine on

    # if a directory or a file exists, use it directly
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d

    # otherwise forward it to index.php
    RewriteRule . index.php

Rewrite the yii2 route and specify the controller to handle when the file does not exist.

class UrlManagerSolr extends UrlManager
{
    public function parseRequest($request)
    {
        $request_uri = $_SERVER['REQUEST_URI'];
        $uris = explode('/', $request_uri);
        $path = Yii::$app->basePath . "/web".$request_uri;
        $fileExist = false;
        if(file_exists($path) == false && strpos($request_uri, "/data/list/file") !== false){
            $_SERVER['REQUEST_URI'] = "list/file.html";
            $_GET['page'] = intval($uris[3]);
        }
        return parent::parseRequest($request);
    }
}

Processed action: Get data from the database and generate a static file corresponding to the path.   

public function actionFile()
    {
        $specialRecommend = new SpecialRecommend();
        $page = empty($_GET['page']) == false ? intval($_GET['page']) : 1;
        $pageSize = 10;
        $rows = $specialRecommend->find()->offset(($page - 1) * $pageSize)->limit($pageSize)->orderBy("sid desc")->asArray()->all();
        $html = $this->render('index', [
            'rows' => $rows,
        ]);
        $path = Yii::$app->basePath . "/web/data/list/file/";
        if(file_exists($path) == false){
            mkdir($path, 0755, true);
        }
        $file = $path . "{$page}.html";
        file_put_contents($file, $html);
        return $html;
    }

The test result is nearly 10 times higher than that of test one. The reason for the performance improvement is that apache directly returns the content of the file when it detects the existence of the file data/list/file/1.html, instead of entering the routing and php processing code of yii2. .
