我们使用 ab 命令(apache 提供的性能测试工具)在该版本中测试 laravel 应用(以目前正在讲的使用laravel开发的博客应用为例)性能,我们模拟 10000 次请求,100 个并发进行压力测试:
ab -n 10000 -c 100 http://blog.app/

  

 
运行结果如下:

这里我们要关注的是红色加粗的文字,即每秒处理请求数,这是衡量系统性能的关键指标。根据系统及硬件配置的差异,数据会有些出入。
现在我们按照“laravel homestead 支持 php 7 ”这一节所述将 homestead 中的 php 升级到 7.0 版本。
使用 vagrant ssh 登录到新添加的 homestead-7 虚拟机,查看 php 版本信息是否正确:

此时在浏览器中访问 http://blog.app 会报错,因为新安装的 homestead 数据库数据为空,需要登录到虚拟机运行如下命令运行迁移并填充数据:
php artisan migrate 

php artisan db:seed

  

 
再次访问就ok了,好了我们继续使用同样的 ab 命令进行压力测试:
ab -n 10000 -c 100 http://blog.app/

经过对比,同一个 laravel 应用在 php 7.0 下的性能比 php 5.6 提高了54%,这是一个很显著的性能提升,当然环境不同数据会有所出入,而且还有更大的提升空间。
