【问题描述】:
我已经用 php 5.5 和 apache 2.4 设置了一个 ubuntu 14.04。
我安装了新的 laravel 5.2。项目中没有数据库连接。
然后我什么时候去app/Http/routes.php并编辑成:
Route::get('/', function () {
return view('welcome');
});
Route::get('/test/direct', function () {
return view('welcome');
});
所以基本上我有 2 条路线只显示欢迎视图。
然后我运行:
ab -n 9999999 -t 300 -c 30 http://xxxxx/laravel52/public
Cpu 从未超过 6%,我得到以下结果:

然后我运行:

如果不是根路由,如果有很多连接,似乎 laravel 会使 cpu 尖峰。这也发生在 laravel 4.2 的全新安装中。
谁能指出为什么会发生这种情况?我真的需要解决这个问题。
我的服务器有一个 8 核 Intel(R) Core(TM) i7-4771 CPU @ 3.50GHz 和 8GB RAM。
谢谢。
