PHP7.3+Swoole4.4 / Go1.13 / MixPHP2.2 / Beego1.12 性能对比

2020-07-25 10:07:35 +08:00

好几年没有做过性能对比了，因为越来越觉得性能并没有那么的重要（相对于生态），今天有时间简单测试一下，因为 Mix v2.1 开始就全部切换为单进程协程模式，因此本次主要测试的是 Co\Http\Server ，测试结果在最后面。

环境

PHP 7.3.12 + Swoole 4.4.14

代码中使用的单进程 Co\Http\Server ，因此需要利用端口复用 (需要 Linux >= 3.10)，开启 12 个进程

<?php 

\Swoole\Process::daemon();

$scheduler = new \Swoole\Coroutine\Scheduler;
$scheduler->set([
    'hook_flags' => SWOOLE_HOOK_ALL,
]);
$scheduler->add(function () {

	$server = new \Swoole\Coroutine\Http\Server('0.0.0.0', 8888, false, true);
	$server->handle('/', function($request, $response){
		$response->end('hello, world!');
	});
	$server->start();

});
$scheduler->start();

Go 1.13.4

Golang 默认使用全部 CPU 线程，因此只需开启一个进程即可。

package main

import (

    "net/http"
)

func main() {

    http.HandleFunc("/", func(writer http.ResponseWriter, request *http.Request) {
        writer.Write([]byte("hello, world!"))

    err := http.ListenAndServe(":9999", nil)

PHP 7.3.12 + Swoole 4.4.14 二次测试

上面减少到 5 个进程依然可以达到 12 进程的性能，我猜测可能是 ab -c 1000 只能达到 12w 左右的并发，也就是说没有打满，需要降低使用的线程数来测试，我们采用 2 个线程重新测试一下。

    http.HandleFunc("/", func(writer http.ResponseWriter, request *http.Request) {
        writer.Write([]byte("hello, world!"))
    })
    err := http.ListenAndServe(":9999", nil)
    if err != nil{
        fmt.Println(err)
    }

}

测试：多跑几次，基本稳定在 106834.75 左右，比 Swoole 性能低了 21.7%，证明 Swoole 确实性能是高于 Go 的 net 库。

一个结论：beego 性能差，doge.

2020-07-25 10:16:07 +08:00
@bazingaterry fasthttp 肯定更强，但是这里的表达的观点的是 PHP 没那么弱 （在 IO 方面）

helloworld 有啥用，整点正常玩意啊，来个最简单的 curd 也成啊，然后就知道所谓的动态语言跑 benchmark 都什么德性了
onanying
2020-07-25 10:29:18 +08:00
@blless 不要轻易下结论，如果性能趋同如何？我打赌 10 块，Mix 一样拥有连接池，协程特性，既然你提了，我费力今天写一个 db 查询的。

这种测试完全就是搞笑，就跟一个 hello world 说明一个语言好坏一样。go 是完全异步的，swoole 之类的只是这个库本身异步，巨量的第三方库甚至 php 自带的标准库很多都废了。类似 python 的 gevent 来个 monkey patch 这种手段也只是治标不治本 谁知道什么地方会有坑等着你。go 第三方库就就不存在这个问题因为人家是语言级的异步。第三方库就不存在这个问题。 要不然为什么 c#用了 async 后标准库里要整那么多 async 开头的方法

ab 和 server 同一台机器可能影响结果，建议分开，另外现在一般都用 wrk 了吧
onanying
2020-07-25 10:35:52 +08:00
@alexkkaa 你这种喷生态的，还算是喷的有点道理，喷查询性能的那是真外行
onanying
2020-07-25 10:38:21 +08:00
@alexkkaa 我开发了 20 几个库处理这些问题，常用的 mysql + redis 么有问题，基于 guzzle 开发的库也没有问题，只能说常用第三方的生态都被改造支持异步了，冷门一些的就确实支持不太好。
alexkkaa
2020-07-25 10:41:04 +08:00
@onanying 这个得标准库支持才有意义，像.net 标准库里增加了很多异步方法，相应的社区第三方库也会使用这些自带的方法。 标准库不支持生态就起不来
onanying
2020-07-25 10:41:31 +08:00
@alexkkaa 还有一点和 py c# 不同的是 php composer 的包都还能用（但是不支持异步了，在调用的那一段时间，但是执行结果完全不受影响，只是影响整体并发性能），这与 py3 和 c# 的生态不兼容的问题完全不同。

2020-07-25 10:44:02 +08:00
@alexkkaa 所以说这个并不会适合普罗大众，但是有能力的团队都能 hold 住。当然方案有很多种比如我正在开发的 mix-go
alexkkaa
2020-07-25 10:45:40 +08:00
@onanying 但是有能力的团队为什么不直接上 go 呢，这不是隔靴搔痒吗
alexkkaa
2020-07-25 10:46:33 +08:00
我不是抬杠只是被这类坑过 发发感慨 哈
onanying
2020-07-25 10:46:38 +08:00
@virusdefender 同样的环境，即便你说的有道理，影响的结果不会很大，这个是多次测试的均值。并且每次执行数值差异非常小。这台测试机器也没有做其他用途。

2020-07-25 10:50:30 +08:00
@alexkkaa 20000+ rmb 的 php (同时会 go) 30000+ rmb 的 go (php 很烂) 你自己算吧，有了框架 15000+ 的 php 都能写。 同时 mix-go 和 mix-php 用法与设计架构完全一样，15000+ 的 php 同时还能写 go 。你自己算算这个账单吧。

@onanying 所以，看见没，去学 go 啊，同学们，学 PHP 没钱途啊!

@onanying 6# 你写呗 ，到时候贴个付款码就行 我跟了。很多人还是一厢情愿认为 IO 密集跟计算能力关系不大，我之前在公司内部也写过框架。除了网络 IO 以外，消耗大的还有数据序列化跟反序列化这一步，数据量越大越明显，甚至很有可能大量 CPU 都消耗在这个步骤。就光加一个序列化我估计 php,python 之流的 benchmark 就直接掉一个档次。

@blless 后端业务常用的就 mysql redis 还有 curl 文件操作等 ，swoole4 已经完美支持了 同步写法，异步执行,swoole 也有了协程 ，常驻内存+协程，确实性能可以媲美 golang 了
