Note! ApacheBench (ab) is installed on macOS by default. You can check that by using ab -h [for help/information] [for checking ab version] ab -V Ref: https://vyspiansky.github.io/2019/12/02/apache-bench-for-load-testing/
ApacheBench doesn’t seem to be capable of ignoring certificate problems (at least some of them) so I wrote this script: #!/bin/bash K=200; HTTPSA=’https://192.168.1.103:443/’ date +%M-%S-%N>wgetres.txt for (( c=1; c<=$K; c++ )) do wget –no-check-certificate –secure-protocol=SSLv3 –spider $HTTPSA done date +%M-%S-%N>>wgetres.txt It’s not as precise as AB, but gives the idea. Does well in comparison tests.
Use the abs.exe tool to test sites with a SSL cetificate
It sounds like you are running out of ephemeral ports. To check, use the netstat command and look for several thousand ports in the TIME_WAIT state. On Mac OS X the default ephemeral port range is 49152 to 65535, for a total of 16384 ports. You can check this with the sysctl command: $ sysctl … Read more
Here is an example of an ab’s test result. I make 1000 requests that with 3 concurrent requests. C:\>ab -d -e a.csv -v 1 -n 1000 -c 3 http://www.example.com/index.aspx This is ApacheBench, Version 2.0.41-dev <$Revision: 1.121.2.12 $> apache-2.0 Copyright (c) 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Copyright (c) 2006 The Apache Software Foundation, http://www.apache.org/ … Read more
ab requires a trailing slash after the URL. This should work: ab -n 2000 -c 25 http://127.0.0.1/
Jmeter tells you how long each request actually took. AB just does some very basic math to get the overall average. So, the direct answer to your question is that jmeter gets it right and ab just makes a rough guess by giving you the mean across everything. But, sure, if you put the two … Read more
ab -n200 -c100 -H “clientId:test-client”-H “token:93e6acff-2ef9-4c85-9d0b-c9948a8ee93b” -v 2 http://127.0.0.1/oauth2/user/client/ -v show request header
This is an issue with dynamic pages, it happens because the Content-Length can vary between the requests. When using ab with such pages you need to use the -l option. -l Accept variable document length (use this for dynamic pages)
You must have the 2.4 version and use -s timeout option. Edit: https://www.wampserver.com/ – includes Apache 2.4.x Win32 and Win64. Deprecated but still available however I not known until when and just not available: You can use my win32-x86 binary (compiled under Visual Studio 2008 from trunk 8 Feb 2013): http://mars.iti.pk.edu.pl/~nkg/ab-standalone.exe (no longer available) http://mars.iti.pk.edu.pl/~nkg/ab-standalone-src.zip (no longer … Read more
