大家都知道做规模小的web服务器的压力测试可以用apache 内置的ab工具,我发现了另一个工具那就是webbench。
webbench是一款linux网站服务器压力测试工具,webbench最多可以模拟3万个并发连接去测试网站的负载能力,个人感觉要比Apache自带的ab压力测试工具好,安装使用也特别方便,参数很少简单易懂.
1、适用系统:Linux
2、编译安装:
wget http://blog.s135.com/soft/linux/webbench/webbench-1.5.tar.gz
tar zxvf webbench-1.5.tar.gz
cd webbench-1.5
make && make install
3、使用:
webbench -c 500 -t 30 http://127.0.0.1/test.jpg
4、测试结果示例:
Webbench - Simple Web Benchmark 1.5
Copyright (c) Radim Kolar 1997-2004, GPL Open Source Software.
Benchmarking: GET http://127.0.0.1/test.jpg
500 clients, running 30 sec.
Speed=3230 pages/min, 11614212 bytes/sec.
Requests: 1615 susceed, 0 failed.
随便说下apache 下的ab用法:
ab测试工具随apache打包发布,所有应用起来十分方便。
ab
根目录: 在apache的根目录下面。
测试例子: ab -n 10000 -c 100 -t 10 http://www.test.com/
参数: -n 表示请求总数, -c 表示并发数. -t 表示请求时间限制
Usage: ab [options] [http[s]://]hostname[:port]/path
Options are:
-n requests Number of requests to perform
-c concurrency Number of multiple requests to make
-t timelimit Seconds to max. wait for responses
-p postfile File containing data to POST
-T content-type Content-type header for POSTing
-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
-y attributes String to insert as tr attributes
-z attributes String to insert as td or th attributes
-C attribute Add cookie, eg. 'Apache=1234. (repeatable)
-H attribute Add Arbitrary header line, eg. 'Accept-Encoding: gzip'
Inserted after all normal header lines. (repeatable)
-A attribute Add Basic WWW Authentication, the attributes
are a colon separated username and password.
-P attribute Add Basic Proxy Authentication, the attributes
are a colon separated username and password.
-X proxy:port Proxyserver and port number to use
-V Print version number and exit
-k Use HTTP KeepAlive feature
-d Do not show percentiles served table.
-S Do not show confidence estimators and warnings.
-g filename Output collected data to gnuplot format file.
-e filename Output CSV file with percentages served
-h Display usage information (this message)
-Z ciphersuite Specify SSL/TLS cipher suite (See openssl ciphers)
-f protocol Specify SSL/TLS protocol (SSL2, SSL3, TLS1, or ALL)
