Usage: ab [options] [http[s]://]hostname[:port]/path
Options are:-n requests Number of requests to perform宅
//一次同时并发的请求数 总的请求数(n)=次数*一次并发数(c)
-c concurrency Number of multiple requests to make-b windowsize Size of TCP send/receive buffer, in bytes
-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 for POSTing, 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-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 attributesare a colon separated username and password.
-P attribute Add Basic Proxy Authentication, the attributesare 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-r Don't exit on socket receive errors.
-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)3.运行 ab -n 100 -c 10 http://www.meetu.hk/ 对 http://www.meetu.hk/ 进行100次请求,10个并发请求压力测试结果。
