Node.js与Go的性能对比

硬件配置：

CPU：Intel(R) Xeon(R) CPU           E5506  @ 2.13GHz  8核  

内存：24G

 

软件：

Go  1.6

Node v6.9.5

 

测试简单输出hello world!，对比Node与Go，Node单线程，公平起见，将Go限制到单核上。

 

---------------------server.js-----------------

consthttp=require('http');
constserver=http.createServer((req,res)=>{
    res.end('helloworld!');
});
server.listen(8087);

PS：GO的限制核是有效的，如果设置为8，效果明显不一样的，见下：
