不知道该如何测试APACHE的性能,可以参考APACHE自带的测试工具AB(apachebenchmark).在APACHE的bin目录下。 ??? -n requests???? Number of requests to perform 参数很多,一般我们用-c和-n参数就可以了.例如: ./ab -c 1000 -n 1000http://127.0.0.1/index.php 这个表示同时处理1000个请求并运行1000次index.php文件. Benchmarking 127.0.0.1 (be patient) Document Path:????????? /index.html.zh-cn.gb2312//测试的页面文档 Concurrency Level:????? 1000//并发数
格式:./ab [options] [http://]hostname[:port]/path
参数:
???//在测试会话中所执行的请求个数。默认时,仅执行一个请求
??? -c concurrency? Number of multiple requests to make
???//一次产生的请求个数。默认是一次一个。?
??? -t timelimit??? Seconds to max. wait for responses
???//测试所进行的最大秒数。其内部隐含值是-n 50000。它可以使对服务器的测试限制在一个固定的总时间以内。默认时,没有时间限制。
??? -p postfile???? File containing data to POST
???//包含了需要POST的数据的文件.?
??? -T content-type Content-type header for POSTing
???//POST数据所使用的Content-type头信息。
??? -v verbosity??? How much troubleshooting info to print
???//设置显示信息的详细程度- 4或更大值会显示头信息,3或更大值可以显示响应代码(404, 200等), 2或更大值可以显示警告和其他信息。-V显示版本号并退出。
??? -w????????????? Print out results in HTML tables
???//以HTML表的格式输出结果。默认时,它是白色背景的两列宽度的一张表。
??? -i????????????? Use HEAD instead of?GET
???//执行HEAD请求,而不是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)
??? //-C cookie-name=value对请求附加一个Cookie:行。其典型形式是name=value的一个参数对。此参数可以重复。
??? -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.
??? //-P proxy-auth-username:password对一个中转代理提供BASIC认证信任。用户名和密码由一个:隔开,并以base64编码形式发送。无论服务器是否需要(即,是否发送了401认证需求代码),此字符串都会被发送。
??? -X proxy:port?? Proxyserver and port number to use
??? -V????????????? Print?version?number and exit
??? -k????????????? Use HTTP KeepAlive feature
??? -d????????????? Do not showpercentiles?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)
??? //-attributes设置属性的字符串.缺陷程序中有各种静态声明的固定长度的缓冲区。另外,对命令行参数、服务器的响应头和其他外部输入的解析也很简单,这可能会有不良后果。它没有完整地实现HTTP/1.x;仅接受某些'预想'的响应格式。strstr(3)的频繁使用可能会带来性能问题,即,你可能是在测试ab而不是服务器的性能。
