Quick Guide to Performance Testing Tools That Save You $$$

Guide to Performance-Testing-Tools

In this age of modern technology, Performance testing has a significant importance for any business application. Performance testing enables you to make your application more scalable, realizable under concurrent users load. At it’s highest level performance testing is used to measure the continuity and application reputation in the market. Multinational organizations based on the latest technologies are now focusing towards their application monitoring and evaluation process to make it more reliable and durable for maximum amount of users at a time.

In recent past many online business companies have shut down their online applications because of inadequate performance under a heavy load of concurrent transactions by multiple users.

Many open source and commercial performance testing tools are available in the market. Commercial performance testing tools (HP Load runner, IBM Rational Performance Tester) are very expensive. Low and Mid-level organizations cannot afford their current license cost.

So there are many free open source and paid performance tools available in the market to facilitate business applications to determine their performance and identify bottlenecks in the system.

Selection of these tools is a tricky process, but we can have guidelines that might help us to choose best tool available and fulfill our performance testing requirements. While choosing an open source performance testing tool you should keep in mind that a single tool cannot support all technologies supported by an application. E.g Open source tool may support http but not AJAX technology. So you need to be very specific about whether the tool supports everything that your application is using.

Tool selection guidelines include :

  1. Protocols support
  2. Recording business application and generate script support
  3. Replay the recorded business application/script support
  4. Correlation and Parameterization support
  5. Multiple Iterations and Runtime controller support
  6. Scripting language support
  7. Network Bandwidth support
  8. Analysis of the Business application and generate the report
  9. Cross-browser Support
  10. Easy to Maintain/Use


Main advantages of using open source tools for performance testing are:

  • Free or Fair price to purchase and maintain
  • Source code is available to extend its functionality if required
  • Easy to share the performance testing results
  • Uses standard language for scripting


  • Limited protocol supported
  • Lack of Analysis
