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.
Thanks.
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.
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.
Try FunkLoad, a functional and performance testing tool for web apps, written in Python.
Try jmeter + jmeter plugins code.
It should be as simple as others.
Grinder, Funkload, SoapUI (only for Soap Services), Neoload (for load test), Charles Proxy
