Offers good scalability and has the ability to integrate with various systems and services
One area where k6 could improve is by introducing a GUI similar to JMeter. While k6 is a powerful tool for performance testing, it leans heavily towards coding. Having a GUI, even if it is a low-code approach, could make it more accessible to a broader audience. It would be beneficial to strike a balance where basic tasks can be performed graphically through a user-friendly interface, while still allowing the flexibility for more complex operations through code, similar to how JMeter operates. This could enhance the user experience and make k6 more approachable for those who may not be as comfortable with scripting.

Centralized cloud testing has improved global load generation and real-time performance insights
The most valuable features I have found in OpenText Core Performance Engineering (LoadRunner Cloud) are that everything is online and centralized, so I do not need to go anywhere to check the configuration and everything. OpenText Core Performance Engineering (LoadRunner Cloud)'s advanced analytics help identify performance bottlenecks because whenever we are executing the test scripts, it shows a good analytics view where we can simply check which APIs are not performing well. The cloud-based load generators in OpenText Core Performance Engineering (LoadRunner Cloud) have benefited my testing setup because we can generate the load across the globe, which was previously a little bit difficult on the on-premises version. The user interface in OpenText Core Performance Engineering (LoadRunner Cloud) is intuitive and this will be easy to communicate and collaborate amongst the team also because sharing the online URL with the team, they can simply check the analysis and everything.

Quotes from Members

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

Pros

"The standout feature of k6 is its strong focus on API performance testing."
"The tool's big advantage is that it is more performance-test oriented for experienced testers who know what they are doing. In a normal working setup, performance engineers frequently work with DevOps and development teams. For these teams, k6 Open Source's syntax is much simpler and easier to understand and apply in the working process."
"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 TCO has been optimized along with the total ROI."
"Even though the cost is expensive, there are good features when compared to all other tools."
"The reports are very relevant to the customers’ expectations."
"It is very easy to set up a load test, to start it and end it, and it is valuable that it is very easy to use."
"From end-to-end, starting from creating the load scenarios, to running them, and then reporting, LoadRunner is the best tool."
"I rate OpenText LoadRunner Cloud ten out of ten."
"Keeping up with DevOps, thus the best feature of StormRunner is that we don't have to build and maintain infrastructure anymore."
 

Cons

"One area where k6 could improve is by introducing a GUI similar to JMeter."
"Some improvements can be made to the solution's user interface"
"The product must provide agents to monitor servers."
"During the initial days of high concurrency testing (300,000 and 600,000) we had issues with the StormRunner infrastructure e.g. graphs disappeared in the middle of a test, and HP had to give an online fix."
"Scriptless automation is an area that can be improved."
"We initially had some problems with the setup as we had an issue while configuring load generators with the tool."
"I would like for there to be better integration with other tools so that when you do load testing you can also do a security check."
"There is a steep learning curve for the product, too."
"When you start a test, it takes times to initiate."
 

Pricing and Cost Advice

Information not available
"It is expensive compared to other tools."
"We make use of virtual user hours. We buy time in the LoadRunner Cloud. It costs around $80,000."
"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 solution’s price is considerably high."
"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."
"The pricing for OpenText LoadRunner Cloud is average."
"There is no monthly or yearly cost but rather, the fees are based on the amount of traffic that you use."
"It's a very expensive solution"
