我在用Mac 上的 Homestead + Vagrant + Virtualbox.
Problem
虽然我发现很多线程/答案如何解决响应时间慢的问题（例如 TTFB），但没有一个起作用。我的响应时间在 25 - 32 秒之间，这对于本地开发来说显然是不可接受的。
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 https://github.com/laravel/homestead/issues/901
并且还阅读并尝试了这些线程中的许多建议：
- Homestead 的反应非常慢 https://stackoverflow.com/questions/37636159/very-slow-responses-on-homestead
- 流浪家园慢 https://stackoverflow.com/questions/25761707/vagrant-homestead-slow
- 自上次请求 60 秒后，vagrant 页面加载缓慢 https://stackoverflow.com/questions/29571079/vagrant-slow-page-load-after-60-seconds-from-last-request
- 加快 Vagrant 上主机和来宾之间的同步延迟（NFS 同步文件夹） https://stackoverflow.com/questions/26818907/speed-up-sync-latency-between-host-and-guest-on-vagrant-nfs-sync-folders
尽管有公认的答案，但没有一个对我有帮助。
禁用 xdebug
我可以这么说禁用 xdebug就像解释的那样here https://christattum.com/disabling-xdebug-in-laravel-homestead/帮我节省了 5 秒。
更改光盘大小
根据建议将虚拟机的磁盘大小从动态更改为固定here https://github.com/laravel/homestead/issues/901#issuecomment-483332495并解释了here https://gist.github.com/christopher-hopper/9755310根本没有帮助（结果更糟）。
按照建议使用 NFS（同步文件夹）here https://stackoverflow.com/questions/26818907/speed-up-sync-latency-between-host-and-guest-on-vagrant-nfs-sync-folders
将 homestead/vagrant 设置为 NFS 也没有任何帮助。
尝试过（流浪文件）：
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']
NFS 在这两种情况下都可以工作，但它并没有改变页面加载时 TTFB 的任何情况。
设置 natdnshostresolver: 关闭
我还尝试按照建议关闭 natdnshostresolverhere https://github.com/laravel/homestead/issues/901#issuecomment-406409231它没有改变任何事情。
调整 Virtualbox 映像
当然，我也尝试过增加 RAM、CPU、显卡等，但正如你所见，这并没有帮助。
任何其他建议
截至目前，我也愿意尝试，例如valet https://laravel.com/docs/6.x/valet或您可以提供的任何其他建议/解决方案。
预先非常感谢！
Update 1
改变nginx.conf在我的虚拟机上（在 @emotality 建议调整之后）确实有一点帮助。为了完整性和可能进行更多调整，这里是 nginx.conf 文件的整个 http 部分。
