我在Mac上使用 Homestead + Vagrant + Virtualbox 。

问题

虽然我发现了很多解决慢响应时间（例如TTFB）的线程/答案，但是它们都不起作用。我的响应时间在25到32秒之间变化，这显然对于本地开发来说是不可接受的。

建议的解决方案

我从这里尝试了很多建议的解决方案：https://github.com/laravel/homestead/issues/901

并且还阅读并尝试了以下这些线程的许多建议：

• Very Slow Responses On Homestead
• Vagrant Homestead slow
• vagrant slow page load after 60 seconds from last request
• Speed up sync latency between host and guest on Vagrant (NFS sync folders)

即使已经接受了答案，但没有一个能帮助我。

禁用xdebug

我可以这么说 像说明的here一样禁用xdebug 可以帮助我节省5秒钟。

更改光盘大小

按照建议here并按照here的说明将VM的磁盘大小从动态更改为固定时，根本没有帮助（结果更糟）。

根据建议here使用NFS（同步文件夹）

也将宅基地/流浪者设置为NFS并没有帮助。

尝试过（无效文件）：

Vagrant.configure("2") do |config|
  config.vm.synced_folder ".","/vagrant",type: "nfs",mount_options:['nolock,vers=3,udp,noatime,actimeo=1']
end

也尝试过（homestead.yaml）

folders:
    -
        map: '/Users/myuser/PhpstormProjects/example.com'
        to: /home/vagrant/code
        type: "nfs"
        options:
            mount_options: ['nolock','vers=3','udp','noatime','actimeo=1']

在这两种情况下NFS都可以正常工作，但是它并没有改变有关页面加载时TTFB的情况。

设置natdnshostresolver：关闭

我还尝试根据建议here关闭natdnshostresolver 它并没有改变任何事情。

调整Virtualbox图像

当然，我也尝试增加RAM，CPU，图形等内容，但是如您所见，这没有帮助。

还有其他建议

截至目前，我也愿意尝试valet或您可以提供的其他任何建议/解决方案。

非常感谢！

在我的VM上更改 nginx.conf （在@emotality建议进行调整之后）确实有所帮助。为了完整性和可能性，可能还要进行一些调整，这是nginx.conf文件的整个http部分。
