问题说明,在vagrant虚拟机中启动cii 框架项目的时候没问题,但在启动laravel项目的时候花费17S,这明显不符合常理吗?
造成此问题的原因，是虚拟机共享文件系统 IO 速度慢所导致的。而一个全新安装的 Laravel 应用响应一个请求时，需要读取 600+ 的文件，瓶颈尤为明显。
补充:以下亲测可行方法
1.本地Mac系统不需要安装,我的是在不清楚的情况下安装了,每次报错,所以卸载就好
sudo rm /etc/exports
sudo touch /etc/exports
sudo chmod -R 777 exports #有权限问题的话加这一步
sudo vagrant halt
sudo vagrant up --provision #在启动过程中,会询问是否允许更改exports文件,直接允许就好vagrant plugin uninstall vagrant-winnfsd #卸载插件
2修改后: Vagrantfile 文件

修改后的/etc/exports 文件,这个是在vagrant up 启动过程中自动生成的

成功启动后:
如果报错
sudo rm /etc/exports
sudo touch /etc/exports
sudo chmod -R 777 exports #有权限问题的话加这一步================以下仅供参考==============
Vagrant虚拟机系统：CentOS6.5
首先要把虚拟机的网络设置成 :private_network 模式。
1、虚拟机安装nfs服务：
centos 5 :
yum -y install nfs-utils portmapcentos 6 :
yum -y install nfs-utils rpcbind2、MAC OS已经集成nfs，只需要修改/etc/eprots文件，如果没有则新建
sudo vi /etc/exports 保持空文件即可3、Vagrantfile文件修改
config.vm.synced_folder ".", "/vagrant", type: "nfs"保存后，使用命令 vagrant reload 重启虚拟机后才会生效，期间会修改MAC OX的 /etc/exports 文件。会提示输入mac账号的密码。输入即可！
2015-02-02最新更新：vagrant官方说明中发现了一段内同
NFS synced folders have a set of options that can be specified that are unique to NFS. These are listed below. These options can be specified in the final part of theconfig.vm.synced_folder definition, along with the type option.
nfs_export(boolean) – If this is false, then Vagrant won’t modify your/etc/exportsautomatically and assumes you’ve done so already.nfs_udp(boolean) – Whether or not to use UDP as the transport. UDP is faster but has some limitations (see the NFS documentation for more details). This defaults to true.nfs_version(string | integer) – The NFS protocol version to use when mounting the folder on the guest. This defaults to 3.
可以设置 nfs_export的属性为true即可忽略文件的修改，会假设已经把文件设置好。
默认采用的是UDP协议。
NFS协议使用的版本：默认为3
nfs 支持windows
vagrant plugin install vagrant-winnfsdvagrant plugin list卸载插件:https://stackoverflow.com/questions/54294057/vagrant-up-problem-sh-netsh-command-not-found
vagrant plugin uninstall vagrant-winnfsdgit commit 报错:
git pull 报错：error: insufficient permission for adding an object to repository database .git/objects
error: insufficient permission for adding an object to repository database .git/objects error: 无法创建树对象解决方案:成功提交文件
在客户端,我的是mac端
sudo chmod 777 -R .git/objects
即可

===================以下供参考,据说不太好使=====================
使用 Homestead 在开发 Laravel 应用程序，经常会遇到网页响应速度缓慢，有时甚至十几秒甚至几十秒才返回响应，极大影响了开发体验：
造成此问题的原因，是虚拟机共享文件系统 IO 速度慢所导致的。而一个全新安装的 Laravel 应用响应一个请求时，需要读取 600+ 的文件，瓶颈尤为明显。
解决问题
解决方案是让虚拟机使用 IO 效率更高的 NFS 挂载方式。
第一步、安装 NFS 服务
我们需要在主机的系统里安装 NFS 服务供虚拟机使用。
Mac 用户默认支持 NFS 挂载。
Windows 用户 需要安装 Vagrant WinNFSd ，在你的 Git Shell （或者其他 Windows Shell）里运行以下命令进行安装：
$ vagrant plugin install vagrant-winnfsdUbuntu 用户 可以使用以下命令安装 NFS 服务：
$ apt-get install nfs-kernel-server第二步、修改配置
接下来修改 Homestead.yaml 文件里的 folders 文件挂载信息，指定挂载的 type 为 NFS：
folders:
- map: ~/code
to: /home/vagrant/code
type: "nfs"第三步、重启并应用虚拟机
因为我们修改了 Homestead.yaml ，需要 --provision 参数来应用虚拟机修改，并使用 reload 来重启虚拟机：
$ vagrant reload --provision结语
以上配置成功后，一般情况下，你应该可以得到 1s 内的响应速度。

setp 1 ：centos安装nfs
yum install nfs-utils rpcbind
setp 2 ：MAC OS已经集成nfs，只需要修改/etc/exports文件，如果没有则新建
setp 3 : Vagrantfile文件修改
config.vm.synced_folder "~/www", "/data", type: “nfs"
注：～／www为mac机器的目录。／data为虚拟机的目录。
保存后，使用命令 vagrant reload 重启虚拟机后才会生效，期间会修改MAC OX的 /etc/exports 文件。会提示输入mac账号的密码。输入即可！
然后，你会发现mac上的~/www 目录和虚拟机上的/data目录是互通的。开始配置你的网站吧window可参考: https://blog.csdn.net/ghostyusheng/article/details/64923272
