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Reporting efficacy and collaboration improve despite outdated features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.

More OpenText Silk Central pros

Cons

"The tool has lots of limitations."

"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."

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

"The installation and tool setup can take some time, since this involves several components."

"The HP tool is overall a little better but much more expensive."

"Reporting needs improvement to provide more customization options in the performance test analyst to build custom reports."

"Sometimes new versions have bugs."

"Support for more protocols is required."

More IBM Rational Performance Tester cons

"Adding the test cases and assigning them to particular testers can be improved."

"It can be a bit slow sometimes, and it has not got some of the modern features many of the other competitors have."

"At this point, we feel that the customization is bad."

"From a test automation perspective, the main feature missing is the ability to schedule executions with only failed tests."

"I think that the portal could be cleaner and faster."

"Better management of mandatory fields."

"We would also like to manage the integration testing end-to-end."

"Product does not respond well on virtual machines because of network and memory issues."

More OpenText Silk Central cons

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."
