Octane+Swoole提升程度测试

测试Octane+Swoole提升程度

写在前面
laravel项目使用octane+swoole对于性能的提升非常显著(220%+的QPS提升),但还是难以与静态语言抗衡。

测试过程
硬件:虚拟机VirtualBox, 1核2G, CPU为i5-8400;
系统: Centos7 + 宝塔;
php环境: 启用opcache, session启用memcached缓存,文件缓存启用redis;

部署项目及引入octane

composer create-project laravel/laravel octance.sw
cd ./octance.sw
## 引入octane
composer require laravel/octane
## 安装octane
php artisan octane:install

安装这一步使用RoadRunner出了很多问题,最后跑起来也没能正常访问,遂放弃使用RR;

使用swoole倒是非常简单,宝塔面板中装好swoole扩展,octane:install时选swoole直接完成。

laravel进行普通的生产环境优化;

composer install --no-dev
## 设置配置文件,关掉debug
vi .env
APP_ENV=production
APP_DEBUG=false
## :wq保存
## 执行优化
composer dump-autoload -o
php artisan optimize

到中件间文件app/Http/Kernel.php中注释掉api下的throttle中间件,以免ab压测时报429的错误

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;然后进行ab压测,一次压测结果如下:

 .\ab -n2000 -c8 http://octane.sw/api/random

测试结果可见,普通优化下,php8的php-fpm能提供110+的QPS;

2, 压测octane+swoole
启动工作进程:

php /path/octane.sw/artisan octane:start --host="0.0.0.0" --port=8080 --workers=4 --max-requests=10000 --task-workers=10

并加入到Supervisor进程守护中;
配置nginx,将所有请求都转发到127.0.0.1:8080
进行ab压测,一次压测结果如下:

octane+swoole的压测的QPS为380+

结论:QPS从110+提升到380+,提升幅度达到220%+,提升很明显,但却低于期望。官方所宣称的QPS高达2000+,明显不能直接套用于生产环境。同时,如果按QPS提升程度来算,重构代码只是为了200%+的提升是否值得也需要好好考虑一下。
