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.

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 useful for performance and load testing."
"Monetary benefits with Apache JMeter are notable since it doesn’t require a licensed version."
"Apache JMeter has aided in that challenge."
"Due to process automation, I don't have to prepare reports, making it the perfect solution."
"If you play within those limitations, it is a really great tool."
"It's open source, so I like that about the product. And there's a lot of community support for it."
"Very easy to download and setup the entire infrastructure (Controller + LGs)."
"It gives accurate results and recommendations that we can implement to enhance the performance of websites."
"I find network traffic testing the most valuable feature."
 

Cons

"I sometimes found the documentation to be not as explanatory as I would've liked it. In the cases that I can think of, I was looking for a rather hand-holding approach with Step A, B, and C, but then I realized that with a product that is open source like this, you can't do handholding. That is because there are so many different uses and different unique environments and setups for it, but I remember thinking a few times that if they only just said this."
"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."
"The stability could be a bit better."
"Running JMeter in GUI mode uses a lot of memory, which means we need to switch to a non-GUI mode when using a heavy load."
"Documentation is not comprehensive, making it difficult to find the right answers."
"In future releases, it would be helpful if there was an integration with ALM Octane."
"Apache JMeter could be a more user-friendly product from the end user's perspective."
"The user interface could be improved."
"The solution could improve by increasing the Gbps speeds and by having better support for storage."
 

Pricing and Cost Advice

"In terms of open-source adoption, it is completely free."
"The solution is open source with no user fees or licenses."
"Apache JMeter is a free tool."
"We use the open source version."
"Since we are using an outsourced solution, it is not paid for by our company."
"This is an open-source solution, and there are no fees."
"The solution is open source."
"I was using the free version of the software."
"The price of the solution is reasonable."
