为什么在 Zend Framework 2 中使用 ClassMapAutoloader 没有获得性能？

Question

在我的公司，我们正在开发一个 ZF2 应用程序，没有程序；-)，现在。我们正处于一个阶段，我们希望通过将应用程序的某些部分公之于众来测试它。

我们准备了一个 STAGE 环境，我现在进行一些性能调整。我读到使用ClassMapAutoloader 比StandardAutoLoader 快得多，例如描述的。 http://samminds.com/2012/11/zf2-performance-quicktipp-2-classmap-autoloading/ 。我确实理解为什么它应该更快，但在我的情况下，我使用 xdebug 分析、WinCacheGring/QCacheGrind 分析了有和没有 ClassMapAutoloader 的站点，它较慢约为 0.2%。

有谁知道为什么这会变慢？

我使用的是 CentOS 和 PHP 版本 => 5.6.12

从相关的 Module.php 中提取：

public function getAutoloaderConfig() {
    return [
        'Zend\Loader\ClassMapAutoloader' => [
            __DIR__ . '/autoload_classmap.php'
        ],
        'Zend\Loader\StandardAutoloader' => [
            'namespaces' => [
                __NAMESPACE__ => __DIR__ . '/src/' . str_replace('\\', '/', __NAMESPACE__)
            ]
        ]
    ];
}

我已经检查过 Autoloader 使用了类映射。

抱歉回复晚了。现在您的应用程序加载半秒 - 准确地说是 0.6 秒。所以我的自动装载机正在做他的工作。您的查询也执行得很快。我还可以想到另外两种方法来加快您的应用程序的速度。

• 第一种方式 - 使用模板映射

找到您的 templatemap_generator.php 文件。它应该在您的vendor/zendframework/zendframework/bin 文件夹中。导航到您的模块文件夹，例如Application 文件夹所在的src, view, config 目录。打开终端并输入 php ../../vendor/zendframework/zendframework/bin/templatemap_generator.php ZF 将在您的模块目录中创建一个模板映射。现在要使用这个模板，只需修改你的 module.config.php 文件。文件结构与 clasmap_autoloader.php 中的类似

return array(
// Telling where the views are
'view_manager' => array(
    'display_not_found_reason' => true,
    'display_exceptions'       => true,
    'doctype'                  => 'HTML5',
    'not_found_template'       => 'error/404',
    'exception_template'       => 'error/index',
    'template_map' => include __DIR__ . '/../template_map.php', // <-- add this line. You can remove `template_path_stack`
),

在您的控制器中为每个操作添加一个视图模板。 公共索引操作（） { $view = 新的 ViewModel(); $view->setTemplate("应用程序/索引/索引"); 返回$视图； }

• 第二种方式 - 在生产环境中使用模块缓存。

假设您的 .htaccess - SetEnv APPLICATION_ENV "development" 中有这一行

在你的public/index.php 文件中，如果你没有做过类似的事情，添加这个：

/**
 * Set global ENV. Used for debugging
 */
if (isset($_SERVER['APPLICATION_ENV']) && $_SERVER["APPLICATION_ENV"] === 'development') {
    define("APP_ENV", 'development');
} else {
    define("APP_ENV", "production");
}

这将确保您在应用程序中拥有一个全局环境，该环境表明调试是打开还是关闭，它可以帮助您避免 DRY 代码。 现在从你的根文件夹打开config/application.config.php

<?php

$modules = [];

if (APP_ENV === 'development') {
    $modules[] = 'ZendDeveloperTools';
    $modules[] = 'BjyProfiler';
    $modules[] = 'SanSessionToolbar';
}

$modules[] = 'Application';
$modules[] = 'Admin';

return [
    // This should be an array of module namespaces used in the application.
    'modules' => $modules,

    // These are various options for the listeners attached to the ModuleManager
    'module_listener_options' => [
        // This should be an array of paths in which modules reside.
        // If a string key is provided, the listener will consider that a module
        // namespace, the value of that key the specific path to that module's
        // Module class.
        'module_paths' => [
            './module',
            './vendor',
        ],

        // An array of paths from which to glob configuration files after
        // modules are loaded. These effectively override configuration
        // provided by modules themselves. Paths may use GLOB_BRACE notation.
        'config_glob_paths' => [
            'config/autoload/{{,*.}global,{,*.}local}.php',
        ],

        // Whether or not to enable a configuration cache.
        // If enabled, the merged configuration will be cached and used in
        // subsequent requests.
        'config_cache_enabled' => (APP_ENV === 'production'),

        // The key used to create the configuration cache file name.
        'config_cache_key' => md5('app_config'),

        // Whether or not to enable a module class map cache.
        // If enabled, creates a module class map cache which will be used
        // by in future requests, to reduce the autoloading process.
        'module_map_cache_enabled' => (APP_ENV === 'production'),

        // The key used to create the class map cache file name.
        'module_map_cache_key' => md5('module_map'),
        // The path in which to cache merged configuration.
        'cache_dir' => dirname(__DIR__)."/data/cache",

        // Whether or not to enable modules dependency checking.
        // Enabled by default, prevents usage of modules that depend on other modules
        // that weren't loaded.
        'check_dependencies' => (APP_ENV !== 'production'),
    ],

    // Used to create an own service manager. May contain one or more child arrays.
    //'service_listener_options' => [
    //     [
    //         'service_manager' => $stringServiceManagerName,
    //         'config_key'      => $stringConfigKey,
    //         'interface'       => $stringOptionalInterface,
    //         'method'          => $stringRequiredMethodName,
    //     ],
    // )

   // Initial configuration with which to seed the ServiceManager.
   // Should be compatible with Zend\ServiceManager\Config.
   // 'service_manager' => [],
];

config_cache_* 将在您的应用投入生产时激活并缓存您的路由配置。您的所有模块路由都将被缓存。此外，如果网站处于生产状态，则不会加载调试模块。 你可以用任何你想要的替换md5('app_config')。
