关于laravel:OctaneSwoole提升程度测试

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：

测试后果可见，一般优化下，php8的php-fpm能提供110+的QPS;

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：

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。
