JMeter

JMeter is well suited for Java applications where the user can script the scenario once and make changes to accommodate for as many numbers of users for load test execution. The image and selection of any files or exporting files scenario is handled well.
It is less appropriate to test Ajax applications where it is required to script click per use.

Go for IBM RPT if:1. You're testing a Java-based Web application with HTTP protocol2. You wanted to distribute the load across machines easily 3. Your team is in learning phase/not really introduced to a wide range of performance testing toolsDo not go for IBM RPT if:1. You wanted to test REST or any other advanced protocols2. Your system under test demands a very high user load3. Your application is written in .NET or any other platform except Java.

Pros

JMeter

  • Easy of use - in generate load like HTTP requests, and processing/analyzing the responses. No coding is necessary at the basic level, just need to understand load testing and the infrastructure being tested.
  • Automatic management of things like cookies to help with session state support - so you don't specifically have to worry about it or handle it
  • Lots of testing/configuration options to suit your needs in making the right load generation (sampling requests), and analyzing the results, including any pre and post processing of the results first. Things like the Beanshell/BSF pre/post processors, response assertion, regular expression extractor, XPath extractor, CSV data set config
  • There is a JMeter cloud service called BlazeMeter that I think would be useful for those that need to scale up high load without provisioning their own systems. I've not personally tried it though, but I recently attended a meetup presentation that highlighted nice useful features that BlazeMeter provides. One should evaluate the service if they are considering JMeter and need to expand beyond existing hardware resources.

  • Data Parameterisation/ Data Correlation is made simpler compared to its competitors
  • Distributed Load Testing is easier to set up
  • Performance metric gathering while a test is in progress
  • Th look and Feel really helps a beginner to understand and work with.

Cons

JMeter

  • Jmeter requires many tweaks with respect to its configuration file and thread properties. users need to edit theses files themselves. There could be some interface where we can edit this fields.
  • Jmeter cannot handle more threads and hangs up when we increase the number of threads. This causes lot of inconvenience. In these situations, user can be notified that such change would be lead to slow performance so that user can do as required. The same appears when we try to view huge files on graph listener.
  • Jmeter should optimize the read and write access to output csv since it acts as overhead to the I/O performance. This affects our test results for the application which we are testing.

IBM Rational Performance Tester

  • Memory utilization could have been improved.(Eats up system's RAM)! It may crash if a test is conducted with the heavy load if adequate RAM is not available in the VM/host machine.
  • Licensing could have been made simpler. IBM's licensing method is difficult to follow.
  • Support for protocols other than HTTP. Not really up to the current trend.

Price, Wiki and user sharing. Having access to the information provided by the developers and other open source providers is key for me. The ability to share information and get answers directly is very important to success in software testing. And the price of this product currently is amazing. Too many companies charge way too much money for products that are far behind in their value and pertinence

I can jump right into a new test plan and start building from scratch. The natural progression from test plan to thread group and then designing the basic format of the process is very streamlined and smooth. With only slight modifications I can build out a very complex model from a very basic beginning.

I have been using JMeter for the last year. By using this tool, you can make sure the system will work under varied loads. It helps us to simulate real time scenarios by creating required virtual users and make sure the application will work under load. Perform load, stress, and stability testing using JMeter.

Alternatives Considered

JMeter

I have used LoadRunner and Silkperformer, and so far Jmeter turns out be the easiest to use of all these. While each of them have their own ROI, Jmeter can be picked by anyone in hours and start testing within a day. While with other tools, we need to get license, install them (takes a while) and setup tests and firewalls, etc.

Cost/Licensing: While JMeter is an opensource testing tool from Apache, compared to IBM RPT and HP LoadRunner, RPT is much cheaper than Loadrunner.Functionality: JMeter provides basic functionalities which are adequate for performance testing, however advanced features are not available (such as load testing with GUI, reporting is very basic etc.). But when it comes to Loadrunner, it offers very broad features and supports a variety of protocols. So in this category, Loadrunner is a winner, but RPT is better than JMeter.Ease of operating: JMeter is easy compared to LoadRunner, but it has old GUI and look and feel is not that great to understand. Also, most of the things are to be done in a command line, non-GUI mode. While LoadRunner is very advanced with many options, which also confusing sometimes. But RPT, on the other hand, maintains a balance between simplicity and offering of different features. So winner: RPT.
