ab使用范例:
要执行 1000 次的 connection, 20 次的 concurrent (并行, 同时):

语法: ab -n 1000 -c 20 http://localhost/

产生出来的结果. 要注意的是以下几个:

§ Time taken for tests: 总共执行花了多久的时间.(以上 1000 次共多久)

§ Requests per second: 每秒平均可以处理多少个 connection.

下面是一个在Windows Azure虚拟机上做的测试，虚拟机性能不怎么样呀（和这个测试相比 ASP.NET Web Api vs Node.js Benchmark, Take 2）。
