locust - Scalable user load testing tool written in Python

•    Python

Locust is an easy-to-use, distributed, user load testing tool. It is intended for load-testing web sites (or other systems) and figuring out how many concurrent users a system can handle. The idea is that during a test, a swarm of locusts will attack your website. The behavior of each locust (or test user if you will) is defined by you and the swarming process is monitored from a web UI in real-time. This will help you battle test and identify bottlenecks in your code before letting real users in.

Apache JMeter - Pure Java application for load and functional testing

•    Java

Apache JMeter may be used to test performance both on static and dynamic resources (files, Servlets, Perl scripts, Java Objects, Data Bases and Queries, FTP Servers and more). It can be used to simulate a heavy load on a server, network or object to test its strength or to analyze overall performance under different load types. You can use it to make a graphical analysis of performance or to test your server/script/object behavior under heavy concurrent load.

jmeter-ec2 - Automates running Apache JMeter on Amazon EC2

•    Shell

This shell script will allow you to run your local JMeter jmx files either using Amazon's EC2 service or you can provide it with a simple, comma-delimited list of hosts to use. Summary results are printed to the console as the script runs and then all result data is downloaded and concatenated to one file when the test completes ready for more detailed analysis offline. By default it will launch the required hardware using Amazon EC2. Using AWS it is much easier and cheaper to scale your test over multiple slaves but if you need to you can also pass in a list of pre-prepared hostnames and the test load will be distributed over these instead. Using your own servers can be useful when the target server to be tested can not be easily accessed from a location external to your test network or you want to repeat a test iteratively.

Tsung - Distributed Load Testing Tool
