I'm looking for a freeware / simpler alternative to JMeter. It is a very complete yet complex tool and all I need is to simulate a number of simultaneous calls to a site, grab stats about performance (time to the response) and see how many concurrent calls it can endure without breaking. Some chart thrown in would be useful.

Use Apache Benchmark (ab). It's a command line tool that ships with apache web server. If you're running *nix, chances are it's already installed on your machine. For example, if you want to send 1000 requests to a web server running on localhost using 10 concurrent threads you would do this:

$ ab -n 1000 -c 10 http://localhost/

It'll spit out a nice report giving you interesting stats such as requests per second, number of failures, and much more.

    if it's not already installed, you can install with sudo apt-get install apache2-utils – Jason Jun 08 '13 at 09:49

    Apache bench covers the most basic case where you just want to bombard a single URL. If you want to do more realistic stress tests, I would recommend Locust (http://locust.io). It's an open-source load testing tool where you define your tests using python code. – heyman May 05 '14 at 19:38

    For those who have realized that JMeter is not built for high loads, the choice is between locust.io and Gatling . Of the two, locust is the simpler one as you can get going in no time . Gatling has more possibilities and therefor more complex – binithb Sep 17 '14 at 10:21
  • If you are a command-line geek like me, this is perfect for you. For more info on how to use this: `man ab`. Thank you! – pegasuspect Aug 07 '20 at 16:55

Maybe you could try Gatling .

It provides a GUI, recorders, reports (response time distribution, requests per second over time,..),...

I think that the biggest difference between gatling and jmeter is that gatling does not use 1 thread for 1 user, but uses async IO. It could be interesting if you have performance issues whith jmeter (and if you cannot use jmeter in a distributed mode)

Try Grinder, it's reasonably simple to use, and can be scripted.

    Grinder is as "complex" as jmeter. So i don't think it Will help. –  Aug 06 '12 at 12:36

Try jmeter + jmeter plugins code.
It should be as simple as others.

Try FunkLoad, a functional and performance testing tool for web apps, written in Python.

  • In addition to that, it requires test cases to be also written in python. In that case, i don't think so it will be viable alternative for jmeter – Amit Jun 28 '12 at 15:15

Grinder, Funkload, SoapUI (only for Soap Services), Neoload (for load test), Charles Proxy
