Siege 教程¶
Siege 是一个 http 负载测试和基准测试工具。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。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。Siege 可以从您选择的预置列表中请求随机的 URL,然后进行压力测试。
安装¶
进入 http://download.joedog.org/siege/ 选择最新版本:

Usage: siege [options]
siege [options] URL
siege -g URL
Options:
-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
-r, --reps=NUM REPS, number of times to run the test.
-t, --time=NUMm TIMED testing where "m" is modifier S, M, or H
ex: --time=1H, one hour test.
-d, --delay=NUM Time DELAY, random delay before each requst
-b, --benchmark BENCHMARK: no delays between requests.
-i, --internet INTERNET user simulation, hits URLs randomly.
-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.
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
使用示例¶
请求 url:
$ siege -c 20 -r 10 http://www.baidu.com
从 urls.txt 中选择 url 请求:
$ siege -c 5 -r 10 -f urls.txt
POST 请求:
$ siege -c 10 -r 5 http://www.xxxx.com/index.php POST UserId=XXX&Sign=cff6wyt505wyt4c
设置请求间隔:
$ siege -c 10 -r 5 -d 3 http://www.baidu.com
