注:本文对于新版本的golang并不使用,go1以后go的性能已经有了比较好的提升,具体测试见: http://www.cnblogs.com/QLeelulu/archive/2012/08/12/2635261.html
听说Go是很不错的语言,了解了一下,一些特性确实很不错。
顺便测试了一下http与node.js的性能对比。
go的代码:
node.js的代码:

从测试结果来看,node.js的HTTP SERVER性能是Go的两倍还多,而且让我比较郁闷的是,在用webbench进行测试的时候,可以看到go是用了我的笔记本上的四个核的CPU的,而node.js当然是只跑在一个核上,而Go居然还比node.js慢这么多。
然后我google,就看到:golang helloworld 45% slower than node.js
求真相!
