在Symfony中改进Composer \ Autoload \ includeFile [英] Improve Composer\Autoload\includeFile in Symfony

问题描述

我已经在Symfony 2.8项目上进行了Blackfire测试，结果表明，大部分时间(超过50％)被435个Composer \ Autoload \ includeFile调用使用

I have made Blackfire test on my Symfony 2.8 project and it shows that most of the time (more than 50%) is used by 435 calls of Composer\Autoload\includeFile

任何建议如何改进它? 清除产品缓存后，我正在使用php composer.phar dump-autoload --optimize.

Any suggestions how to improve it? I am using php composer.phar dump-autoload --optimize after I clear cache for prod.

我将APC用于元数据，并将查询缓存用于原则，而我的app.php文件如下所示:

I use APC for metadata and query cache for doctrine and my app.php file looks like this:

<?php

use Symfony\Component\HttpFoundation\Request;

/**
 * @var Composer\Autoload\ClassLoader
 */
$loader = require __DIR__.'/../app/autoload.php';
include_once __DIR__.'/../app/bootstrap.php.cache';

// Enable APC for autoloading to improve performance.
// You should change the ApcClassLoader first argument to a unique prefix
// in order to prevent cache key conflicts with other applications
// also using APC.
/*
$apcLoader = new Symfony\Component\ClassLoader\ApcClassLoader(sha1(__FILE__), $loader);
$loader->unregister();
$apcLoader->register(true);
*/

$kernel = new AppKernel('prod', false);
$kernel->loadClassCache();
//$kernel = new AppCache($kernel);

// When using the HttpCache, you need to call the method in your front controller instead of relying on the configuration parameter
//Request::enableHttpMethodParameterOverride();
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);

推荐答案

此函数如下:

function includeFile($file)
{
    include $file;
}

因此，这不是Composer本身的问题.这里没有什么要优化的.您只是包含了很多文件.

So this is not the issue with Composer itself. There's nothing to optimize here. You're just including a lot of files.

无论如何，请仔细查看您的app.php.

Anyway, take a closer look at your app.php.

首先，您编写了我使用APC(...)，然后粘贴了包含以下内容的代码段:

First, you've wrote I use APC (...), and then pasted code snippet containing this:

// Enable APC for autoloading to improve performance.
// You should change the ApcClassLoader first argument to a unique prefix
// in order to prevent cache key conflicts with other applications
// also using APC.
/*
$apcLoader = new Symfony\Component\ClassLoader\ApcClassLoader(sha1(__FILE__), $loader);
$loader->unregister();
$apcLoader->register(true);
*/

我建议遵循此提示，并取消注释以下几行代码.

I would suggest to follow this hint and uncomment these a few lines of code.

此外，APC配置可能还会进行优化.

Also there may be possible optimizations in APC configuration.
