Symfony2 和 Twig 在 vagrant box 中的表现

问题：

即使是打开一个空白页面（如登录表单），也需要很长时间。正如在分析器中看到的，大部分时间都花在了 twig 渲染上：

Twig taking 3.5 seconds to render

我尝试过的：

1. 正如您在 Vagrantfile 中看到的，NFS 已启用。不知道如何测试它
2. 阅读this 和this。您在上面的屏幕截图中看到的测试是在这些更改完成后运行的

Answer 1

如果您的主机操作系统是 Win（在我的情况下为 Windows 7 x64），为了使其在 vagrant 中更快地工作，您需要：

1. 添加this 修复。我还在列表中添加了“prod”环境：

public function getCacheDir()
{
    if (in_array($this->environment, array('dev', 'test', 'prod'))) {
        return '/dev/shm/project/cache/' .  $this->environment;
    }

    return parent::getCacheDir();
}

public function getLogDir()
{
    if (in_array($this->environment, array('dev', 'test', 'prod'))) {
        return '/dev/shm/project/logs';
    }

    return parent::getLogDir();
}

1. 利用 NFS 修复 I/O 性能。问题是我很困惑：在 synced_folders 中设置 nfs=true 选项并不意味着您正在通过 NFS 进行连接。我的主机操作系统是 Win7，我必须安装 NFS server 才能使其工作。请注意，它不是免费的。 以下是我必须分享的两个文件夹：

另外，使用 synced_folder 挂载对我不起作用，因为 NFS 服务器只监听特定的 IP 地址，所以我不得不注释掉这个：

config.vm.synced_folder "../../../project", "/var/www", type: "nfs",:nfs => true

并把它改为：

$script = <<SCRIPT
  sudo mount 192.168.178.40:/d/project /var/www/ && sudo mount 192.168.178.40:/d/project/_conf /etc/apache2/sites-enabled && sudo service apache2 restart
SCRIPT

  config.vm.provision "shell", inline: $script, privileged: false, run: "always"

，其中 192.168.178.40 是开放 NFS 端口的 IP。您可以从您的 gurest 操作系统扫描它，例如地图。

1. 您还需要安装名为 vagrant-winnfsd 的 vagrant 插件。可以通过以下方式完成：

vagrant 插件安装 vagrant-winnfsd

Answer 2

我认为这不是树枝性能的问题，而是 VirtualBox/vagrant 中的目录共享问题。尝试在 VirtualBox 中启用 I/O 缓存。
