About Yii's method to improve the performance optimization of concurrent numbers

This article mainly introduces the performance optimization method of Yii to improve the number of concurrency. It has a certain reference value. Now I share it with you. Friends in need can refer to it

1. Turn on YII's APC cache

• Add under the config/main.php components component:

   'apccache'=>array(
              'class'=>'system.caching.CApcCache'
        ),

• Download php_apc.dll, file Put it under php/ext, it may be more troublesome to search....

• Add the php_apc extension in php.ini:

   extension=php_apc.dll
   apc.rfc1867 = on
   capc.max_file_size = 100M
   upload_max_filesize = 100M
   post_max_size = 100M

  Restart apache, use Function info(), check whether there is apc extension.

• Usage:

      Yii::app()->apccache->get(id);
      Yii::app()->apccache->set(id,value,time);

2. Use yiilite.php
Import yii.php into the entry file index.php , change to introduce yiilite.php

<?php
    error_reporting(E_ERROR);
    $config = dirname(__FILE__) . &#39;/protected/config/main.php&#39;;
    defined(&#39;YII_DEBUG&#39;) or define(&#39;YII_DEBUG&#39;, false);
    defined(&#39;YII_TRACE_LEVEL&#39;) or define(&#39;YII_TRACE_LEVEL&#39;, 3);
    //require_once &#39;../../xq_cgi-yii/framework/yii.php&#39;;
    require_once &#39;../../xq_cgi-yii/framework/yiilite.php&#39;;
    Yii::createWebApplication($config)->run();

Note:

• Open apc cache and then introduce yiilite.php, because there are some classes in this file that are not currently used will also be loaded in.

• If apc cache is not turned on, website performance will be reduced.
