Preskoči na sadržaj Mjerenje performansi web poslužitelja alatom ab (Apache HTTP server benchmarking tool) Apache HTTP Server uključuje ApacheBench, kraće ab, koji služi za mjerenje performansi web poslužitelja. Specijalno, unutar slike httpd na Docker Hubu, ab je dostupan kao naredba ab koju je moguće pokrenuti navođenjem te naredbe nakon imena i verzije slike: $ docker run httpd:2.4 ab: wrong number of arguments Usage: ab [ options ] [ http [ s ] :// ] hostname [ :port ] /path Options are: n requests Number of requests to perform -c concurrency Number of multiple requests to make at a time -t timelimit Seconds to max. to spend on benchmarking This implies -n 50000 -s timeout Seconds to max. wait for each response Default is 30 seconds -b windowsize Size of TCP send/receive buffer, in bytes -B address Address to bind to when making outgoing connections -p postfile File containing data to POST. Remember also to set -T -u putfile File containing data to PUT. Remember also to set -T content-type Content-type header to use for POST/PUT data, 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.
