Performance testing has become central and reporting has provided clear insights for our teams

We do have command prompt related or CLI functionality with Apache JMeter, so it is easier. However, since it is open source, much work has not been put into the GUI part. The GUI could definitely be enhanced. One drawback which I can see when I compare it with other tools is the amount of cache that it uses, the memory that it uses. It becomes very difficult to work with when we have a lot of requests that need to be processed. Anything more than 10,000 requests becomes a bit of an unfavorable task when using Apache JMeter altogether. Otherwise, it does help anyone who is starting off with performance testing.

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.

Quotes from Members

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

Pros

"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 new version of the solution is stable."

"For those who do not want to spend money on tools then this solution would be a good choice."

"The solution is comparable to LoadRunner because it works with multiple plugins but is free to use."

"It's open source, so I like that about the product. And there's a lot of community support for it."

"When there's a high number of TPS I can achieve more transactions per seconds given the hyper-limitations."

"Apache JMeter is well-known and widely used among developers, particularly on popular developer forums. While it may not have the most user-friendly interface, it offers strong support through official manuals and various articles from companies providing load testing services. The tool is free, has a substantial community, and serves as a fundamental choice for testers, especially those new to performance testing. While other tools like K6 may be more developer-oriented, JMeter's affordability and accessibility make it suitable for those without extensive performance testing experience."

"For the load test which requires high transactions per second to be achieved, in the range of 15K transactions per second, this is a very good tool to use and the biggest advantage is that it is free."

More Apache JMeter pros

"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."

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

"All IBM testing tools are really well integrated."

"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."

Cons

"At present, if the number of virtual users increases beyond 10,000 when testing, then it results in a Java heap which causes the solution to crash."

"It's not stable. With every new release, they come up with newer features, which aren't always very stable."

"One area for improvement is the ability to decrease load suddenly during tests. Currently, we need to use multiple separate JMeter instances to simulate reductions in load, which isn't ideal."

"Recording the script is also not flexible in JMeter."

"One drawback which I can see when I compare it with other tools is the amount of cache that it uses, the memory that it uses."

"It does not support recording SSL."

"Reporting feature can be improved to provide better test results."

"Given that Apache JMeter is a free and open-source tool, documentation improvement may not be a major concern, as it is mostly contributed on a voluntary basis. The essential information is already available. However, in terms of the interface, there are occasional bugs, and the tool may not address them as quickly as some users would like. Fixing defects and bugs might take a considerable amount of time, with users sometimes having to wait for several months or even a year for the next release to address specific issues."

More Apache JMeter cons

"Rational Performance Tester supports cloud technology in the version 8.7, playing test scripts back on the cloud is not stable."

"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."

"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."

"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."

Pricing and Cost Advice

"This is an open-source solution, so there are no licensing costs associated with it."

"There are operational costs related to using Amazon Cloud, but the tool itself."

"The tool is open-source."

"Since it's free, there's no need for extensive support or improvements in pricing."

"The main reason we chose Apache JMeter is that it is cost-effective and easy to use. There is no need to pay for additional services. Additionally, it does not require additional payment to vendors. The solution is open-source and free."

"We are using the free version."

"Apache JMeter is a free tool."

More Apache JMeter 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."
