这是一个创建于 的文章,其中的信息可能已经有所发展或是发生改变。

去年的时候,曾经简单对比了一下golang和nodejs的http模块的性能,见: golang与node.js的http对比测试

那时golang还没发布go1,http模块比nodejs差得很远。

go1出来已经有一段时间了,我知道go的http模块性能已经有比较大的提升,但是最近依然见到有人提起去年写的那篇文章,为避免产生对golang的误解,对于go1的最新测试结果如下。


测试是在Ubuntu 12.04 64位系统下进行的:

qleelulu@nb:~$ uname -a
Linux nb 3.2.0-25-generic #40-Ubuntu SMP Wed May 23 20:30:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

qleelulu@nb:~$ sudo dmidecode | grep CPU
Socket Designation: CPU
Version: Intel(R) Core(TM) i5 CPU M 480 @ 2.67GHz (注:双核4线程)

 

go的版本:

qleelulu@nb:~$ go version
go version go1

 

nodejs的版本:

qleelulu@nb:~$ node -v
v0.8.6

 

单CPU测试

nodejs是单进程,只使用一个CPU,所以这里golang在代码中需要限制为只使用一个CPU。

go的代码: (注:go代码都是使用 go build xxx.go 编译)

package main

import (
    "fmt"
    "log"
    "net/http"
    "runtime"
)

func main() {
    // 限制为1个CPU
    runtime.GOMAXPROCS(1)

    http.HandleFunc("/", func(w http.ResponseWriter, r  *http.Request) {
        fmt.Fprint(w, "Hello, world.")
    })

    log.Fatal(http.ListenAndServe(":8080", nil))
}

单CPU测试go和nodes的ab测试对比结果:

单CPU测试go和nodes的ab测试对比结果

从单CPU的测试结果来看,golang和nodejs的性能差不多,golang要稍微比nodejs的性能好一点。
但是从CPU的使用率来看,特别是在webbench测试的时候,测golang的时候,我笔记本上4个CPU的使用率都在50%左右,而测nodejs的时候,则明显是有一个CPU的使用率是在100%,其他的在30%左右。 
对于nodejs, 一个CPU占用去到100%是很正常的,V8引擎也从来都是非常吃CPU的。对于golang为什么限制为仅使用1个CPU,而测试时4个CPU的使用率都去到50%,可能和go对于goroutine的调度方式有关系。

 

多CPU测试

go测试代码
因为是在同一台机器上测试的,所以限制使用的CPU数为机器的CPU数减一。

package main

import (
    "fmt"
    "log"
    "net/http"
    "runtime"
)

func main() {
    // 限制为CPU的数量减一
    runtime.GOMAXPROCS( runtime.NumCPU() - 1 )

    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        fmt.Fprint(w, "Hello, world.")
    })

    log.Fatal(http.ListenAndServe(":8080", nil))
}

nodejs测试代码
使用cluster,使用CPU数量减一个CPU

var cluster = require('cluster');
var http = require('http');
var numCPUs = require('os').cpus().length;

if (cluster.isMaster) {
    // Fork workers. fock num of CPUS - 1 works
    for (var i = 1; i < numCPUs; i++) {
        cluster.fork();
    }

    cluster.on('exit', function(worker, code, signal) {
        console.log('worker ' + worker.process.pid + ' died');
    }); 
    cluster.on('fork', function(worker, code, signal) {
        console.log('worker ' + worker.process.pid + ' is online');
    }); 
} else {
    // Workers can share any TCP connection
    // In this case its a HTTP server
    http.createServer(function(req, res) {
        res.writeHead(200);
        res.end("hello world.");
    }).listen(8080);
}

nodejs多CPU webbench测试时,CPU使用率

 

多CPU测试结果来看,总体上来说go和nodejs的性能也还是差不多。
但从ab测试的结果来看,go的QPS要比nodejs高一点,
而从webbench测试结果来看,nodejs的QPS要比go高,但是go的bytes/sec又要比nodes高,可能是go的http返回头比nodes要稍微大一点的原因。

多CPU测试时的CPU使用情况和单cpu测试时的情况差不多,
golang对4个cpu的占用率都在70%左右,
而node则是对3个CPU的占用在90%以上,还有一个CPU的占用率则要稍微低点。 

 

从整体来看,golang和nodejs的http模块性能不相上下。
go1的性能还是比较喜人的,加上go语音的简洁,是个不错的选择(目前可能go的一些第三方模块都不是很成熟)。
