服务器并发能力测试 Apache Beach

1.打开windows cmd（以下数据兼为windows xp平台运行数据） 2.Cd 至Apache bin目录。 3.运行ab.exe ( ApacheBench command line utility) Java代码 Usage: ab [options] [http://]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 -b windowsize Size of TCP send/receive buffer, in bytes -p postfile File containing data to POST. 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 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 -r Don't exit on socket receive errors. -h Display usage information (this message) Usage: ab [options] [http://]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 -b windowsize Size of TCP send/receive buffer, in bytes -p postfile File containing data to POST.
