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 hostname[:port]/path Options are: -n requests Number of requests to perform -c concurrencyNumber 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.
