记录 WebBench、Siege服务器压力测试工具说明以及使用。

WenBench

WebBench是一个在linux下使用的非常简单的网站压测工具。它使用fork()模拟多个客户端同时访问我们设定的URL，测试网站在压力下工作的性能，最多可以模拟3万个并发连接去测试网站的负载能力。

#Siege

一款开源的压力测试工具，可以根据配置对一个WEB站点进行多用户的并发访问，记录每个用户所有请求过程的相应时间，并在一定数量的并发访问下重复进行。

-V, --version             VERSION, prints the version number.
-h, --help                HELP, prints this section.
-C, --config              CONFIGURATION, show the current config.
-v, --verbose             VERBOSE, prints notification to screen.
-q, --quiet               QUIET turns verbose off and suppresses output.
-g, --get                 GET, pull down HTTP headers and display the
                          transaction. Great for application debugging.
-c, --concurrent=NUM      CONCURRENT users, default is 10
-i, --internet            INTERNET user simulation, hits URLs randomly.
-b, --benchmark           BENCHMARK: no delays between requests.
-t, --time=NUMm           TIMED testing where "m" is modifier S, M, or H
                          ex: --time=1H, one hour test.
-r, --reps=NUM            REPS, number of times to run the test.
-f, --file=FILE           FILE, select a specific URLS FILE.
-R, --rc=FILE             RC, specify an siegerc file
-l, --log[=FILE]          LOG to FILE. If FILE is not specified, the
                          default is used: PREFIX/var/siege.log
-m, --mark="text"         MARK, mark the log file with a string.
-d, --delay=NUM           Time DELAY, random delay before each requst
                          between .001 and NUM. (NOT COUNTED IN STATS)
-H, --header="text"       Add a header to request (can be many)
-A, --user-agent="text"   Sets User-Agent in request
-T, --content-type="text" Sets Content-Type in request

使用举例

1000个并发访问http://www.youku.com并重复请求100次

1	siege -c 1000 -r 100 http://www.youku.com

在urls.txt中列出所有的网址

1	siege -c 200 -r 100 -f urls.txt

随机选取urls.txt中列出所有的网址

1	siege -c 200 -r 100 -f urls.txt -i

不等待返回结果,2000个并发随机选取urls.txt重复请求100个

1	siege -c 2000 -r 100 -f urls.txt -i -b

指定http请求头请求

1	siege -H "Content-Type:application/json" -c 200 -r 100 -f urls.txt -i -b

POST请求

1	siege -c 1000 -r 100 http://www.a.com/ POST p1=v1&p2=v2
