10个用户1个并发=100个用户1个并发 相等吗？

[lumengabc]

如题。

还有就是 这个-n 后面的请求数 是指用户数吗？
是指：10个用户 请求服务器时， 可能有1个并发 或1-10个并发，或者可能0个并发？

ab -n 10 -c 1 http://localhost/a.php
ab -n 100 -c 1 http://localhost/a.php
ab -n 1000 -c 1 http://localhost/a.php

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) 借助在线翻译，不难看懂吧？ 你 ab -n 10 -c 1 http://localhost/a.php 表示 10 个请求，并发数为 1
