1、简要说明：

Apache Bench 是Apache的网站性能测试小程序，Windows平台下的程序名简称ab.exe，要想获得这个80k的可执行程序，用户需要下载整个Apache Httpd软件包！还需要将其安装到电脑上，确实比较麻烦。

Webbench也是一款网站性能测试小程序，可以获得网站的吞吐率、传送速度等基本性能指标。该程序是在Linux下编程的，在Linux下编译安装使用都很方便，但在Windows 下的程序却没有。

为了方便起见，我将ab.exe 小程序单独拷贝出来，并且下载了webbench的源码，使用CodeBlocks程序和Cygwin64，将源码编译了一下，生成Windows7 环境下可执行的文件webbench.exe ，方便在一个平台下同时使用2个程序，进行网站性能测试。

4、测试命令及结果分析

ab.exe -n 15000 -c 100 http://www.abc.com/

# -n 15000总共发送的1.5万个访问请求N个

# -c 100模拟100个用户同时访问C个；

# 结果分析：

#   Concurrency Level:  模拟并发用户数（命令行中输入的数据）C个

#   Time taken for tests: 完成整个测试的时间T秒

#   Requests per second: 服务器性能（在当前并发下每秒能处理的请求数）=N/T个

#   Time per request: (mean)从用户的角度计算，每个请求平均花费时间=T/（N/C）
#       解释：每个用户发送N/C个请求，共花费T秒，每个请求平均花费时间=T/（N/C）

#   Time per request:(mean, across all concurrent requests)从服务器角度计算，完成每个请求的平均花费时间=T/N

#   Transfer rate: 传送速率

webbench.exe -c 100 -t 5 http://www.abc.com/

# -c 100模拟100个用户同时访问；

# -t 5 持续5秒钟测试时间

# 需要测试的网址 http://www.abc.com/ ，注意只测网站名时，结尾要加/

#

# Speed pages/min 每分钟多少个请求， Speed pages/sec 每秒钟多少个请求

# bytes/sec  传送速率

# Requests: 总共完成的请求数

5、注意事项

！！！不要对公共网址发送大量访问请求！！！可用于自己的网站上线前的性能测试。

6、使用帮助

C:\>ab --help

ab: wrong number of arguments

Usage: ab [options] [http://]hostname[:port]/path

Options are:

-n requests     Number of requests to perform

-c concurrency  Number of multiple requests to make at a time

-t timelimit    Seconds to max. to spend on benchmarking

This implies -n 50000

-s timeout      Seconds to max. wait for each response

Default is 30 seconds

-b windowsize   Size of TCP send/receive buffer, in bytes

-B address      Address to bind to when making outgoing connections

-p postfile     File containing data to POST. Remember also to set -T

-u putfile      File containing data to PUT. Remember also to set -T

-T content-type Content-type header to use for POST/PUT data, eg.

'application/x-www-form-urlencoded'

Default is 'text/plain'

-v verbosity    How much troubleshooting info to print

-w              Print out results in HTML tables

-i              Use HEAD instead of GET

-x attributes   String to insert as table attributes
