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.

Performance testing has supported web app peak analysis but needs better setup and smarter scripting
Regarding points for improvement for OpenText Enterprise Performance Engineering (LoadRunner Enterprise), I see that features are not being fully developed yet. If OpenText could think about bringing AI features into the tool, it could save maximum time in scripting or make scripting effortless, particularly in correlation, which is where the complexity involved in script development exists. If any AI features could replace or eliminate more manual work on the correlation part, that is where we could see a game-changing improvement for the tool. OpenText Enterprise Performance Engineering (LoadRunner Enterprise) can be positioned very well in the market. However, I see that the basic correlations are only being handled by the autocorrelation engine in the LoadRunner tool, and I would expect a few improvements to handle even complex correlation problems so that the tool can be appropriately positioned compared to their peers.

Quotes from Members

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

Pros

"All IBM testing tools are really well integrated."
"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."
"IBM Rational integrates the testing software as Rational Test Workbench, which is quite convenient and efficient as it is able to automate the test scripts."
"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."
"Using service virtualization, we are able to accelerate the testing and development activity."
"Our customers think of the following benefits as ROI of using HP Performance Center: Reducing downtime in operations phase that may come due to load on system by fixing or customizing their application to afford the maximum number of concurrent users they expect Prior knowledge of their system limitation and its break point, may let them take precautions steps at application server or network level to prohibit overload traffic that may crash their system."
"We are able to connect and run tests from different locations with this tool."
"For me, the test coverage and the performance and load testing aspects are valuable."
"The most beneficial features of the solution are flexibility and versatility in their performance."
"With the latest updates, it is very comprehensive and one of the best products of the sort."
"The most valuable aspect of Micro Focus LoadRunner Enterprise is the overall support it has for a lot of different applications and defined domains."
"For me, LoadRunner stands out, especially with its reporting capabilities, the graphs that can be generated, and the unique feature of measuring our application's response alongside our infrastructure metrics, such as CPU, memory, or disk usage, all presented in graph form. This is something other applications struggle to match."
"The analytics and reporting features provide beneficial impacts on my organization, and the scalable testing environment is very beneficial for my performance testing processes."
 

Cons

"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."
"Rational Performance Tester supports cloud technology in the version 8.7, playing test scripts back on the cloud is not stable."
"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."
"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."
"Implementing custom functions is bit tedious job, as ECMA script does not support some of the standard java-script functions, Also the Script editor window is not user friendly."
"A room for improvement in Micro Focus LoadRunner Enterprise is that it should take multiple exhibitions for a particular scenario and have automatic trending for that. This will be a very useful feature that lets users look into how many exhibitions happened for the scenario and their performance, and you should be able to see the data within the Performance Center dashboard. For example, there's one scenario I'm focusing on multiple times in a month, and if I check five times, there's no way for me to see the trend and find out how it went with those five exhibitions. It would be great if the Performance Center has a view of all five exhibitions, particularly transaction by transaction, and how they happened. If Micro Focus LoadRunner Enterprise shows you the time trends, information about one exhibition to another, and how each performed, it'll be an immense feature, and that should be visible to every user. Reporting should be simpler in Micro Focus LoadRunner Enterprise. If I did a scenario with one exhibition now, and I did that scenario again, then I should be able to schedule that scenario for the exhibition, and if that scenario is executed multiple times, there should be the option to turn it into a single view that shows you all the transactions, how the performance was, what the trend graph is for a particular time, etc."
"Dashboard creation should be implemented, so we can get the results in a desired format."
"The debugging feature needs to include graphs."
"OpenText LoadRunner Enterprise doesn't support some mainframe protocols. We had to build scripts to access the interface."
"Canned reports are always a challenge and a question with customers because customers want to see sexy reports."
"The initial installation of OpenText Enterprise Performance Engineering (LoadRunner Enterprise) was difficult. I faced many difficulties in understanding which versions to use or which buttons I needed to configure for my injectors in the servers."
"Browser compatibility. IE is no longer the only browser out there, so providing users the choice of what browser to use would be great!"
"Reporting should be simpler in Micro Focus LoadRunner Enterprise."
 

Pricing and Cost Advice

"The pricing is a little bit on the higher side, although it is really good."
"It doesn't really concern me. Licensing is on a yearly basis."
"They have a much more practical pricing model now."
"The prices would differ depending on the number of licenses you need. I wouldn't maybe compare it to any other tools. I rate the price as seven out of ten."
"We used the Professional version and then moved to the enterprise version. We have subscribed to 1000 user licenses. The tool will be super expensive if we take up 5,000 user licenses. We have to limit ourselves on testing."
"We purchased the license via SAP."
"It does everything you could hope for in a performance testing solution. It's not cheap."
"I give the cost a one out of ten."
"This solution can be expensive."
"There is an ROI. What LoadRunner does, is it prevents failures when there are many, many concurrent users in the systems of a company."
