Executive SummaryUpdated on Dec 28, 2025

IBM Rational Test Workbench and OpenText Core Performance Engineering (LoadRunner Cloud) compete in the field of software testing and performance engineering. The data indicates that LoadRunner Cloud holds an edge due to its innovative capabilities, although IBM Rational Test Workbench excels in features and pricing.

Features: IBM Rational Test Workbench provides powerful automated testing, broad integration with other tools, and detailed reporting, making it feature-rich. In contrast, LoadRunner Cloud offers robust performance testing, real-time analytics, and cloud-based flexibility, standing out with its scalability and real-time insights.

Room for Improvement: IBM Rational Test Workbench could enhance its deployment speed and reduce the initial setup complexities. Additionally, integrating more real-time analytics and improving cloud flexibility could boost its competitiveness. LoadRunner Cloud may improve by offering more detailed reporting options, reducing initial infrastructure costs, and expanding integration capabilities with additional third-party tools.

Ease of Deployment and Customer Service: IBM Rational Test Workbench offers a straightforward on-premise deployment but may require more initial setup time, supported by responsive customer service.

Good reporting and interface, but supports limited types of protocols and requires low-level script editing

It should have more interfaces. In terms of interfaces or protocols, what you can do with Rational is far limited as compared to other products out there. What it does, it does great, but it only gives you limited types of protocols. It supports between 8 to 15 types of protocols, whereas other test tools give you 20 to 30 types of protocols with which you can do testing and convert to script. It records Javascript-based scripts, and you got to know a little bit of Java to basically be able to edit them, but the level of editing you got to do is very low. I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script.

User-friendly features facilitate monitoring while support could be more responsive

I am satisfied with OpenText LoadRunner Cloud as a product, but the ticket resolution time is concerning. The technical personnel are not able to fix issues quickly, which becomes problematic during critical situations. Compared to previous support, I notice that while experts previously resolved issues immediately, current experts take more time to resolve issues, which is the main challenge we are facing. They are now lacking regional support, which takes more time than it used to. My suggestions for improvements to OpenText LoadRunner Cloud would be to have specific experts available who can resolve issues more quickly, as delays can impact project timelines significantly.

Quotes from Members

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

Pros

"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."

"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."

"The solution is easy to use."

"The most valuable feature is having load generators in countries where we don’t have access to them."

"The fact that the solution supports multiple protocols such as open source, VuGen, TruWeb, TruClient, and SAP is very important because these protocols help us to concentrate on what is really needed to produce performance tests. If something is not supported, you have to use other tools or find other ways of assimilating loads."

"The most valuable feature is that we do not have to accommodate the load-testing infrastructure in our own data center."

"It's a fast product, so you don't have much trouble in terms of maintenance overhead. You don't want to just look into configuring load generators, look for upgrades, and end up having that take up a lot of your time. With this solution, you just log in and you start using it. This means that there is a huge benefit in terms of the overhead of maintaining the infrastructure and the maintenance effort."

"The usability and ability to integrate with other solutions is quite good. When I use it in on Azure, then Red Hat is the most likely solution I use. When I use AWS, then I tend to use Lambda functions. In either case, it works well and you can use it either way."

"OpenText LoadRunner Cloud eliminates the need for our own testing infrastructure when running tests."

"One of LoadRunner's standout features is its extensive support for various TechStacks and protocols."

Cons

I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script."

"There are a number of things that they can do to simplify the tools, but the most important thing that they need to do is simplify the installation."

"Its scripting features need improvement."

"Scriptless automation is an area that can be improved."

"The product must provide agents to monitor servers."

"Some improvements can be made to the solution's user interface"

"The analysis feature in OpenText LoadRunner Cloud requires improvement. In-depth analysis tools found in the standalone LoadRunner analysis, such as graph merging and setting granularity, would be beneficial."

"An area for improvement is analytics on why response times are slow from certain countries."

"Improvements to the reporting would be good."

"We are trying to put it into a complete CI/CD pipeline, but there are still some challenges when you try to run it through different protocols. The challenges are around how you can containerize applications. There are some limitations to some protocols, such as desktop. And when it comes to database testing, there are some things that we can't do through CI/CD."

Pricing and Cost Advice

"It doesn't really concern me. Licensing is on a yearly basis."

"The pricing is a little bit on the higher side, although it is really good."

"There is no monthly or yearly cost but rather, the fees are based on the amount of traffic that you use."

"We make use of virtual user hours. We buy time in the LoadRunner Cloud. It costs around $80,000."

"LoadRunner always had expensive pricing. At my company, we used to evaluate LoadRunner, but we stuck with Silk Performer because its pricing was always better in the past. I do feel that I got a fair deal this time. Our value-added reseller and our sales guy worked hard to give us a fair deal. I feel that we got a fair deal. We did not go for the pay-as-you-go deal. I did an upfront package. I prefer that. I want to know what my costs are."

"It is neither costly nor cheap. It is not too high and not too low. I know the price of other tools, and LoadRunner Cloud's price is in the medium range."

"Pricing is dependent on what you're referring to. If you're talking about the cloud, it's likely competitive. However, if you're talking about the on-premise version, professional or enterprise licenses are required. Prices are on the high side. They are not cheap."

"The pricing is very reasonable and the licensing is straightforward."

"The solution’s price is considerably high."

"It is expensive compared to other tools."
