服务器基准测试：服务器可以处理多少个 http 请求？

Question

I am creating an application which sends the measurement data every 200 ms from mobile phone to the server. The data have to be processed in real-time, but I noticed that the difference between the sent time and the time of process start is getting bigger and bigger so I have to find the point where the requests get stuck.

I am sending the requests in the httpwebrequest form (http://testserver/submitdata?ax=value1&ay=value2&az=value3) and on the server I am using RESTful service created in WCF.

Anyway is there any benchmarking tool that could test how many requests can be handled by the server or is there any other practical way to determine what can be the maximum number of requests per seconds handled without causig the delay?

Thanks!

Answer 1

Apache Benchmarking (ab)工具可能是一个很好的方法（它适用于任何 HTTP 服务器，而不仅仅是 Apache）。

Answer 2

ab is indeed a descent solution. In its simplest form you can run

ab -c 10 -n 100 http://my.page.com/

in order to call the server 100 times and keep 10 requests running concurrently. I have an example at my blog .
