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.

Reporting efficacy and collaboration improve despite outdated features
I do this for my own benefit, and it has nothing to do with any company views. I work as a permanent employee for a government department. OpenText Silk Central is coming to the end of its support, so we will have to move to something else, but I do not know what the other solution will be. Automation is quite immature at our place. It has only really started, so there is no integration with OpenText Silk Central. I would give it a rating of 7 out of 10; it could be 7.5. It just lacks certain features that would make it a higher grade if it had more modern features.

Quotes from Members

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

Pros

"It has improved our visibility of reporting and simplifying performance testing for larger projects/programs."
"Comprehensive Rational Performance Tester results allow testers to identify bottlenecks in the systems under test."
"This tool is very scalable, and for large scale tests, i.e., 5000 virtual users and up, it performs very well."
"Customization and extensions made in Java is valuable because this can help you set elements to improve your results."
"ROI is big because we do not need vendors to assist some with performance testing."
"It can support both web applications and mobile applications, and in certain cases, it can also support testing of desktop applications or software-based applications. You can write web applications, mobile applications, and software-based applications."
"The setup was straightforward, it depends on the company's regulations and infrastructure policies."
"It's definitely helped in scaling the performance of our application."
"The reporting is probably the most valuable feature."
"This solution adds value because we are able to get the right information at the right time, which helps us to make the right decisions."
"It helps us to manage the test cases efficiently, and it also supports integration with Jenkins."
"With SilkCentral, I can have a macro-view of all my tests."
"Every Waterfall and Agile project should be using Silk Central."
"Issues and Defect Management."
"If you are an enterprise site that needs a real customizable test and defect management solution, one that is easy to use and with a good level of out-of-the-box functionality and integration options, Silk Central is a good choice."
"It would certainly be worth the cost, but you need to be committed to using it long term."
 

Cons

"It was complex."
"The HP tool is overall a little better but much more expensive."
"The installation and tool setup can take some time, since this involves several components."
"Sometimes new versions have bugs."
"We had open many PMRs for problems found in the products, and I'm not sure if all of them have been fixed."
"As intuitive as a product can be, its use could still benefit from a decent set of manuals or guides."
"The tool has lots of limitations."
"Now, the price slightly expensive especially if you are in small-medium company, but if you are in a medium-high company, and need the powerful tools with IBM great name, just use it."
"Adding the test cases and assigning them to particular testers can be improved."
"Product does not respond well on virtual machines because of network and memory issues."
"Better management of mandatory fields."
"I think that the portal could be cleaner and faster."
"I have used HPE Quality Center, HPE ALM, JIRA, and Rally. They are much better tools than Silk."
"It can be a bit slow sometimes, and it has not got some of the modern features many of the other competitors have."
"Although I once met an issue where I created a test case and deleted it immediately, this test case still existed in the database and was still being included in our execution runs, and I had no idea how to completely remove this unused test case."
"At this point, we feel that the customization is bad."
 

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."
"The cost of this tool, in terms of licensing, is not large."
