golang与node.js的http模块性能对比测试(go1)

golang与node.js的http模块性能对比测试(go1)

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))
} 

golang请求结果:

nodejs单CPU webbench测试时,CPU使用率如下:

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))
}

Speed = 753080  pages/min,  1380698  bytes/sec. 

golang多CPU webbench测试时,CPU使用率如下:

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 );
}

Requests per second:      12851.16  [#/ sec] (mean)
Requests per second:      13005.08  [#/sec] (mean) 

nodejs的多CPU webbench测试结果,共测试5次,结果如下: 

$ webbench -t  30  -c  200  http: //  127.0.0.1:8080/ 
 
Speed = 791932  pages/min,  1148301  bytes/ sec.
Speed = 786516  pages/min,  1140448  bytes/ sec. 
Speed = 797336  pages/min,  1156140  bytes/ sec.
Speed = 783182  pages/min,  1135619  bytes/ sec.
Speed = 785206  pages/min,  1138551  bytes/sec. 

nodejs多CPU webbench测试时,CPU使用率如下:

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)。
