Leveraging cost-effective customization with powerful plugins but complexity reduction needed
Apache JMeter offers plugins for reporting and preparing test scenarios. It allows recording to customization, letting you download plugins to connect with databases or external systems. Despite being open source, it offers features comparable to paid tools, and its ability to customize and expand is particularly useful. Additionally, its open-source nature makes it cost-effective.

We can edit captured transactions and organize them by those for which we require performance metrics, but it lacks a set of manuals or guides that would take out some guess work.
It is used to capture and generate HTTP tests. The capture process is very easy. After this, we edited the captured transactions to organize them into the sections or transactions we require performance metrics for (i.e. splash page, user authentication, main pageload, logout, etc.). This editing process is easy to perform with the interface provided in Rational Performance Tester Finally, Rational Performance Tester has an import/export feature that has been extremely useful. We have used it to export our complete test library and import it into another Rational Performance Tester server with no loss or issues. This allows for platform test migrations and backup.

Quotes from Members

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

Pros

"It is easy to set up."
"The recording and playback functionality is helpful."
"The most valuable feature for us is the available information on the forums and to be able to discuss and get answers from the people that are involved in using this tool."
"It gives accurate results and recommendations that we can implement to enhance the performance of websites."
"It is open source as well as relatively extendable. It allows us to extend and add additional functionality and features. Its deployment is also very easy."
"When there's a high number of TPS I can achieve more transactions per seconds given the hyper-limitations."
"The solution is scalable."
"They can easily view the results and gain valuable insights."
"It can support both web applications and mobile applications, and in certain cases, it can also support testing of desktop applications or software-based applications. You can write web applications, mobile applications, and software-based applications."
"Technical support is very good. I'm very satisfied with the assistance we've received so far."
 

Cons

"The plug-ins make the reports heavy and they have to be run in non-GUI mode."
"The tool needs improvements related to client-side metrics, integrating with tools like YSlow or HTTP Watch, and enhancing mobile testing capabilities."
"The solution is not user-friendly, there is no framework for autocorrelation or parameterization."
"Considering the kinds of tests we are performing here, where we launch several tests at the same time as a batch request, JMeter is not the best tool for the job. Those kinds of things could be done easily with other tools, like T6."
"Because so much is being done these days with authentication processes, a better system for either getting bearer tokens or some kind of token-based authentication prior to executing APIs would benefit the product. It is there, and you can do things. It is just not real clean at this point. There should be a better authentication process for JMeter or some automation or better guidelines for gaining and utilizing tokens on the fly."
"In future releases, it would be helpful if there was an integration with ALM Octane."
"The reporting section of the solution can be better."
"I need to consider it further because as features increase, it might become more complicated, and my goal has always been simplicity. Currently, I have to focus on other tasks, and I'm handling multiple responsibilities, so I can't juggle everything at once. However, if you ask me, I believe EJB covers most functionalities that are crucial. One improvement I'd suggest is adding a graphical aspect to the Gateway, making it a bit more colorful. Unlike JMeter, which lacks color, having a bit of color in the graphical aspects would be beneficial. Overall, for the essential features, EJB should work fine."
"The solution is not easily scalable. If you want to extend the solution, you need to purchase a different kind of license. You also have to work with the IBM team to assist in scaling."
"There are some features that Micro Focus LoadRunner provides, but they are not available in IBM Rational Performance Tester. They should include such features. It can also have more reports similar to what HP provides. It might also need some improvement in terms of the tools and support for other technology areas. Certain technologies are not supported by every tool. They need to support all sorts of technologies and platforms on which web applications and mobile applications are built. They need complete support for all sorts of technologies."
 

Pricing and Cost Advice

"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."
"This is an open-source product."
"It is open source. There are no licensing costs associated. If you need enterprise support, you'll probably end up paying for a license. You would also factor in the infrastructure cost, but that's not significant."
"We are using the free version."
"We didn't pay licensing fees for Apache JMeter because it's an open-source tool. We only paid for the machines where we installed Apache JMeter modules."
"The solution is free of cost as it is open source."
"Apache JMeter is an open-source solution, so it's free to use."
"The price of Apache JMeter is good. The selling rate is quite effective and the limited users with a multi-region-related execution."
"It is much cheaper than Micro Focus LoadRunner. We need perpetual licenses. Support is included in the first sale. After that, you need to renew support every year."
