golang与node.js的http对比测试
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：
（注：是用8g, 8l编译的）
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！
