Measuring Web Application Performance using Open Source Tools

Listen on the go!

“If your page does not load within 5 seconds, 50% of customers abandon your site”, that statement speaks a lot in itself about the increasing need of customers for high speed access to web applications. And with mobile web also causing significant traffic to websites and web applications, it is important to have the performance of your web application checked

With the need for analyzing the performance of your web application increasing, it is a good idea to evaluate some of the popular open source Performance testing tools. We will talk about why you should use an Open source performance test tool for your Performance testing needs and give an overview of some of the popular Open source performance test tools.

Why choose Open Source Performance Test tool:

  • No licensing cost – a commercial load testing tool can really burn your pockets when you want to test with heavy number of virtual users
  • Generate (almost) infinite amount of load on the web application without any additional licensing costs. The only limitation would be the resources available
  • Create your own plug-ins to extend the analysis and reporting capabiltiies
  • Integrate with other open source and commercial tools to drive end to end test cycles

Some of the Popular Open Source Performance Test tools:

Apache J Meter

Apache J Meter is an open source load testing tool built on the Java Platform. This testing tool is developed to test load test functional behavior and performance testing. It supports testing on static and dynamic resources such as Servlets, Java Objects, Perl Scripts, FTP servers, Data Bases, etc. It requires JVM 1.4 or higher to perform. Although it was designed initially to test web applications, today its scope has widened to other test areas.

With a vast user community and ever expanding list of Plugins, JMeter is a favorite for many organizations when it comes to Performance, stress and load testing.

Load UI

Load UI is a very popular open source stress testing tool used for web application performance testing. It supports testing of numerous web protocols such as AMF, REST, JMS, JDBC and web sites. Many testers agree that LoadUI is one of the most interactive and user-friendly testing tools around. This tool is integrated with a functional testing tool soapUI, which adds to its effectiveness. During the testing phase it allows testers to create, configure and update their tests. LoadUI features a high graphic interface that makes testing easier.

LoadUI also comes as LoadUI Pro to extend the features that the open source version provides.

Open STA (Open System Testing Architecture)

Open STA is the abbreviation for Open System Testing Architecture and it is built around COBRA. This GUI based testing tool is used by testers for load analyzing and load testing. This is a complex testing tools and is known to perform heavy test load for scripted HTTP and HTTPS. Here, the tests are performed using simple scripts, recordings and it also takes into account various results and statistics. During load tests, Open STA graphs resource utilization information from application servers, web servers, operating platforms and database servers that help in further analysis.


Using the Java implementation of Python (Jython), The Grinder is a script-only, feature rich load testing platform. Possibly the most powerful lightweight free load testers on the market, but also the most difficult to master. No GUI to speak of, very little in the way of examples… but at least it has a good FAQ. It isn’t useful for Front End Automation, but otherwise The Grinder is flexible and infinitely useful if you can master it. This is the programmer’s preferred load testing tool.

The Performance Engineering team at Cigniti has helped many customers identify the key bottlenecks and helped fixing them.
