测试 Octane+Swoole 晋升水平
硬件：虚拟机 VirtualBox, 1 核 2G，CPU 为 i5-8400;
零碎: Centos7 + 宝塔;
php 环境：启用 opcache, session 启用 memcached 缓存，文件缓存启用redis;
部署我的项目及引入octane
composer create-project laravel/laravel octance.sw
cd ./octance.sw
## 引入 octane
composer require laravel/octane
## 装置 octane
php artisan octane:install装置这一步应用 RoadRunner 出了很多问题，最初跑起来也没能失常拜访，遂放弃应用 RR;
应用 swoole 倒是非常简单，宝塔面板中装好 swoole 扩大，octane:install时选 swoole 间接实现。
对 laravel 进行一般的生产环境优化；
composer install --no-dev
## 设置配置文件，关掉 debug
vi .env
APP_ENV=production
APP_DEBUG=false
## :wq 保留
## 执行优化
composer dump-autoload -o
php artisan optimize到中件间文件 app/Http/Kernel.php 中正文掉 api 下的 throttle 中间件，免得 ab 压测时报 429 的谬误
测试以下内容：在控制器中返回一个 0 -100 的随机数，控制器代码如下
function random()
{$i = mt_rand(0, 100);
return response()->json([
'code' => 0,
'msg' => 'random:' . str_pad($i, 3, '0', STR_PAD_LEFT)
]);
}
1，压测 php-fpm
配置 Nginx 转发到 php-fpm；而后进行 ab 压测，一次压测后果如下：

2, 压测 octane+swoole
启动工作过程：
php /path/octane.sw/artisan octane:start --host="0.0.0.0" --port=8080 --workers=4 --max-requests=10000 --task-workers=10并退出到 Supervisor 过程守护中；
配置 nginx，将所有申请都转发到 127.0.0.1:8080
进行 ab 压测，一次压测后果如下：

100% 118 (longest request)对 octane+swoole 的压测的 QPS 为 380+
论断：QPS 从 110+ 晋升到 380+，晋升幅度达到 220%+，晋升很显著，但却低于冀望。官网所声称的 QPS 高达 2000+，显著不能间接套用于生产环境。同时，如果按晋升程序来算，重构代码只是为了 200% 的晋升是否值得也须要好好考虑一下。
