基于Swoole重构OpenCart启动代码后性能测试

状况

打开webbench测试，200客户端，60秒。并发只有265page/min。

[root@li1205-86 ~]# webbench -c 500 -t 60 http://swoole-opencart.shyclouds.com/
Webbench - Simple Web Benchmark 1.5
Copyright (c) Radim Kolar 1997-2004, GPL Open Source Software.

Benchmarking: GET http://swoole-opencart.shyclouds.com/
500 clients, running 60 sec.

Speed=265 pages/min, 82524 bytes/sec.
Requests: 265 susceed, 0 failed.

整体CPU利用率只有10%-15%。

解决

代码问题

开了8个进程，也启动了8个进程，但实际只有1个进程在干活。
一通google发现Swoole\Http\Server启动参数设置不对.

$http = new Server("127.0.0.1", 9000, SWOOLE_PROCESS, SWOOLE_SOCK_TCP);

$http->set(array(
    'task_worker_num' => 8,
    'daemonize' => 1,
));

改为

$http = new Server("127.0.0.1", 9000, SWOOLE_PROCESS, SWOOLE_SOCK_TCP);

$http->set(array(
    'worker_num' => 8,        # worker数量
    'max_request ' => 100,    # 一个worker最大处理请求数
    "dispatch_mode" => 1,     # 1.轮训，2.固定，3.抢占，
));

测试

试试不同worker数量情况：worker_num = 8, 16, 32

• worker_num = 8

总结

• worker=8表现不佳，不能充分利用系统资源
• worker=16和32差别不大，更多需要数据库端优化。前端php服务器cpu利用率已经稳定。我们这里使用worker_num=16的数据来做对比。

• 性能指标对比 pages/min

遗留问题

• 整理重构后的opencart代码
• 测试可用性
