Shashidhara Allalappa - PeerSpot reviewer
Extensive Protocol Support and Precise Reporting Elevate Testing, Though GUI Usability Needs Improvement
The GUI of Apache JMeter is not that user-friendly because we have many proxies, and we have to record through the proxy. With the limited SSL we have, we cannot use it for UI, which is a drawback. However, Apache JMeter is really good for REST APIs. I don't think there are any other areas other than the GUI that I would want improved about Apache JMeter; it is generally good and supports multiple protocols.
NalinGoonawardana - PeerSpot reviewer
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.
VictorHorescu - PeerSpot reviewer
Ability to test almost every tool in the companies I enter and performs well in a distributed environment
It would be beneficial if LoadRunner could optimize resource usage, especially for protocols that require significant resources, like TrueClient, which interacts directly with the UI. If they could improve resource usage, like ingest or for the load generator, using less CPU or RAM memory, that would be great. That's where I have problems. In real time, when they ask for 5,000 or 10,000 concurrent users, I have to provision a lot of virtual machines to define this load. Then there are situations with certain platforms, especially document management platforms, where the technology is so weird that normal LoadRunner protocols cannot detect it. So, in that case, I have to use that special TruClient protocol. I have to use the TruClient protocol, which actually clicks on the object. Despite the SQL technology, I can still create a script and test for performance. So what I would appreciate a lot is if this protocol would require less resources on a normal virtual machine. I can use fewer concurrent users with TruClient protocols as opposed to almost one hundred with HTTP/HTML. As opposed to many more with HTTP/HTML from, let's say, JMeter. So, optimization at that level for resource consumption by OpenText would be much appreciated.

Quotes from Members

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

Pros

"It's very easy to install, and it's very easy to code and develop the script."
"When someone in our organization wants to test web applications, they use Apache JMeter since they face no hurdles while using the solution."
"What I like best about Apache JMeter is its user-friendly GUI because even if you don't have very good coding knowledge or understanding, or even if you don't come from a development background, you can still use the solution with just a few clicks. This is what's unique about Apache JMeter, in comparison with other tools in the market. As Apache JMeter is open source, when there's a missing feature, you can search in several community blogs for plugins that you can use to modify Apache JMeter to meet your requirements, and this is another advantage."
"The distributed load testing is very good with Apache JMeter."
"The recording and playback functionality is helpful."
"JMeter's open-source nature allows us to create scripts easily, add any number of users during load tests, and handle large volumes of data without additional cost."
"JMeter is easy to use for a user who doesn't have too much knowledge of programming or certain languages."
"We find the load testing feature valuable."
"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."
"The standout feature of k6 is its strong focus on API performance testing."
"It is mostly user-friendly and usable."
"Support is nice, quick, and responsive."
"It has offered me some reliability against other products, like JMeter or some other tools."
"The most valuable aspect of Micro Focus LoadRunner Enterprise is the overall support it has for a lot of different applications and defined domains."
"The tool is very easy to set up and get running."
"The fact that you can have tens of thousands of virtual users and just expand an army of load generators to hammer on whatever application you're testing."
"We are delivering fine performance results and performance recommendations using Performance Center."
"LoadRunner Enterprise's most valuable features are load simulation and creating correlation for parameters."
 

Cons

"Currently, the integration pipeline is implemented by using Jenkins or a similar tool platform. These are continuous integration tools. As far as I know, integration is done by using custom scripts. It would be good if the integration with a continuous integration pipeline, like Jenkins or Hudson, can be done out of the box without using a script."
"What needs improvement in Apache JMeter is the very high load requirements when you want to scale it beyond certain thresholds. For example, small to mid-range testing is very easily done with Apache JMeter, but if you scale and increase the load, then it would be a problem because the tool consumes a lot of resources, probably because Apache JMeter provides an enriched UI experience, so it consumes a lot of memory and requires high CPU usage. This means you have to manage your infrastructure, or else you'll have high overhead expenses. As Apache JMeter is a heavyweight tool, that is an area for improvement, though I'm unsure if Apache can do something about it because it could be a result of the way it's architected. What I'd like to see from Apache JMeter in the future is for it to transition to the cloud, as a lot of cloud technologies emerge around the globe, and a lot of people prefer cloud-based solutions or cloud-native tools. Even if a company has a legacy system, it's still possible to transition to the cloud. I've worked with a company that was an on-premise company that moved to the cloud and became cloud-native. If Apache JMeter could transition to the cloud, similar to k6, then it could help lessen the intense resource consumption that's currently happening in Apache JMeter."
"Scalability is somewhat of an issue, which I would rate around five or six. For runs involving a thousand or more users, JMeter presents a problem because of memory and related issues."
"They can improve it a little bit in terms of distribution load testing. We struggled with it during the distribution. In terms of reporting, runtime monitoring is not currently included, and it should be included. They can also improve it on the reporting side in terms of the comparison of the reports. They can also focus more on integration with CI/CD. Currently, people are using their own customized tools. It would be nice if Apache can provide some standard tools and procedures for integration with CI/CD tools like DPR. There are some tools, but it would be nice if official standard tools and procedures are available."
"Until now, JMeter is not supporting most of the protocols."
"Report generation needs to be improved. It is quite difficult to get to."
"The user interface is a little bit tricky."
"You really need a technical team in order to really utilize the product."
"One area where k6 could improve is by introducing a GUI similar to JMeter."
"Canned reports are always a challenge and a question with customers because customers want to see sexy reports."
"Integration can be tricky during the setup process."
"The TruClient protocol works well but it takes a lot of memory to run those tests, which is something that can be improved."
"The support team needs to be more coordinated."
"It's not that popular on the cloud."
"It would be good if we could look forward at the future technology needs we have. I would like to see Micro Focus provide more customer awareness around how LoadRunner can fulfill requirements with Big Data use cases, for example, where you do performance testing at the scale of data lakes... when it comes to technologies our company has yet to adopt, I would like to see an indication from Micro Focus of how one does performance testing and what kinds of challenges can we foresee. Those kinds of studies would really help us."
"The price of this solution could be less expensive. However, this category of solutions is expensive."
"OpenText LoadRunner Enterprise needs to improve reporting."
 

Pricing and Cost Advice
