本文最新 url: Apache 壓力測試
在 apache 本身的套件中, 有個叫 ab(ApacheBench) 的程式.
ApacheBench 主要是用來測試 apache 執行效率.
ab 參數: Usage: /usr/sbin/ab [options] [http[s]://]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 -p postfile File containg data to POST -T content-type Content-type header for POSTing -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: zop' 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 -s Use httpS instead of HTTP (SSL) -h Display usage information (this message) ex: 要執行 1000 次的 connection, 20 次的 concurrent (並行, 同時). 語法: ab -n 1000 -c 20 http://localhost/abc.php 產生出來的結果. 主要要注意的是以下幾個. Time taken for tests: 總共執行花了多久的時間.(以上 1000 次共多久) Requests per second: 每秒平均可以處理多少個 connection.
