golang與node.js的http對比測試

這是一個建立於 的文章，其中的資訊可能已經有所發展或是發生改變。

註：本文對於新版本的golang並不使用，go1以後go的效能已經有了比較好的提升，具體測試見： http://www.cnblogs.com/QLeelulu/archive/2012/08/12/2635261.html

 

聽說Go是很不錯的語言，瞭解了一下，一些特性確實很不錯。

順便測試了一下http與node.js的效能對比。

go的代碼：

（註：是用8g, 8l編譯的）

node.js的代碼：

 

ab測試結果：

webbench測試結果

==** Node.js **==

從測試結果來看，node.js的HTTP SERVER效能是Go的兩倍還多，而且讓我比較鬱悶的是，在用webbench進行測試的時候，可以看到go是用了我的筆記本上的四個核的CPU的，而node.js當然是只跑在一個核上，而Go居然還比node.js慢這麼多。

然後我google，就看到：golang helloworld 45% slower than node.js

求真相！
