问题:

即使打开空白页面(如登录表单)，也要花费太长时间.正如在探查器中看到的那样，大部分时间是由树枝渲染渲染的:

When opening even an empty page like login form, it takes too long. As seen in profiler, the majority of time is taken by twig render:

嫩枝需要3.5秒的渲染时间

我尝试过的事情:

已启用NFS.不确定如何测试
阅读此和此.完成更改后，您在上面的屏幕截图中看到的测试已运行

as you see in Vagrantfile, NFS is enabled. Not sure how to test it
Read this and this . The test you see on the screenshot above was run after those changes are done

推荐答案

为了使它在流浪汉中更快地工作，以防您的主机操作系统为Win(在我的情况下为Windows 7 x64)，您需要:

In order to make it work faster in vagrant in case your host OS is Win (Windows 7 x64 in my case), you need to:

添加此修复程序.我还向列表添加了"prod"环境:

add this fix. I also added 'prod' environment to the list:

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();
}

通过使用NFS修复I/O性能.事情是让我感到困惑的:在synced_folders中设置nfs = true选项并不意味着您正在通过NFS连接.我的主机操作系统是Win7，必须安装 NFS服务器才能使其正常运行.请注意，它不是免费的.这是我必须共享的两个文件夹:

Fix I/O performance by utilizing NFS. The thing is that I was confused: setting nfs=true option in synced_folders does NOT mean you're connecting through NFS. My host OS is Win7 and I had to install NFS server in order to make it work. Note that it's not free.Here are two folders I had to share:

另外，使用synced_folder挂载对我来说不起作用，因为NFS服务器仅侦听特定的IP地址，因此我必须对此进行注释:

Also, mounting with synced_folder did not work for me, as NFS server was only listening on specific IP address, so I had to comment out this:

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

并改为:

$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是打开NFS端口的IP.您可以使用例如nmap.

,where 192.168.178.40 is the IP where NFS ports are open. You can scan it from yout gurest OS with, e.g. nmap.

您还需要安装名为vagrant-winnfsd的流浪汉插件.可以通过以下方式完成:
