CEO at Xcelliti

Supports web and mobile applications, very scalable, very stable, and wonderful support

There are some features that Micro Focus LoadRunner provides, but they are not available in IBM Rational Performance Tester. They should include such features. It can also have more reports similar to what HP provides. It might also need some improvement in terms of the tools and support for other technology areas. Certain technologies are not supported by every tool. They need to support all sorts of technologies and platforms on which web applications and mobile applications are built. They need complete support for all sorts of technologies.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"ROI is big because we do not need vendors to assist some with performance testing."

"It's one of the most cost-effective products on the market."

"It has improved our visibility of reporting and simplifying performance testing for larger projects/programs."

"Customization and extensions made in Java is valuable because this can help you set elements to improve your results."

"This tool is very scalable, and for large scale tests, i.e., 5000 virtual users and up, it performs very well."

"Comprehensive Rational Performance Tester results allow testers to identify bottlenecks in the systems under test."

"Real time view and its inbuilt root cause analysis tools is something which I like the most."

"Once you are used to this tool, it is user friendly and provides very good analysis for web applications."

More IBM Rational Performance Tester pros

"The most valuable feature is code coverage."

"Complete test management tool."

"Customizable dashboards show how healthy the project is and task distribution ensures every team member gets notified about their performance and no one gets lost in what to do."

"The Parasoft Concerto has enabled the company's test teams to automate the most common and trivial tests which is saving time and delivering consistency."

"It really helps developers execute scenarios through DTP and share reports/results across the teams."

Cons

"User friendliness can be better, as this is one area where it lacks."

"The solution is not easily scalable. If you want to extend the solution, you need to purchase a different kind of license. You also have to work with the IBM team to assist in scaling."

"We had open many PMRs for problems found in the products, and I'm not sure if all of them have been fixed."

"There are some features that Micro Focus LoadRunner provides, but they are not available in IBM Rational Performance Tester."

"Sometimes new versions have bugs."

"Installation and configuration processes, and support from IBM all need to be improved."

"Since it is Java-based, it is expected to be a resource eater on Windows."

"Support for more protocols is required."

More IBM Rational Performance Tester cons

"Parallel execution: It would help if multiple executions could be done at the same time."

"Customer service is 6/10. Technical support is 6/10."

"The solution's speed has room for improvement."

"Needs individual licence for every new slot which requires a code to be provided by the vendor and activated manually."

"Parallel execution: It would help it multiple executions could be done at the same time."

Pricing and Cost Advice

"It is much cheaper than Micro Focus LoadRunner. We need perpetual licenses. Support is included in the first sale. After that, you need to renew support every year."

"Costly."
