Bash - Use ApacheBench to measure the performance of HTTP web servers

# ab -n <number-of-requests> -h "User-Agent: <user-agent>" <url> # send 100 requests to example.com and change the User Agent to foobar/1.0 ab -n 100 -H "User-Agent: foobar/1.0" http://example.com/somepath/somefile.xyz # send 10 concurrent requests to example.com at the specific IP ab -n 10 -c 10 -H "Host: example.com" http://192.168.1.1/ : ' 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 -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. `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. -q Do not show progress when doing more than 150 requests -l Accept variable document length (use this for dynamic pages) -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. -m method Method name -h Display usage information (this message) -Z ciphersuite Specify SSL/TLS cipher suite (See openssl ciphers) -f protocol Specify SSL/TLS protocol (SSL3, TLS1, TLS1.1, TLS1.2 or ALL) '
