TusharShankar - PeerSpot reviewer
QA Manager at Synechron
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.

Open-source and flexible but needs client-side scripting
It's an open-source tool and supports a lot of plugins and custom code, which allows integration with other tools like Azure and AWS. Also, the APIs tested with SoapUI can be directly used, avoiding the need to create collections like in Postman. The client-side scripting, if incorporated, would provide a complete solution for performance tests. It can handle user distribution and transaction throughput distribution effectively.

Quotes from Members

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

Pros

"The solution's initial setup is easy."
"API testing, Database Testing, and MQ testing can be done with ease."
"It's open source, so I like that about the product. And there's a lot of community support for it."
"The best features Apache JMeter offers in my experience are that it is an open source tool, free of cost, and it can generate multiple users."
"It is scalable. It is cloud-based."
"Regardless of whether it is used for personal performance, load, volume, UI test, or functional test, Apache JMeter is the best tool on the market."
"The most valuable feature of this solution is that it is free."
"We appreciate that the solution is free to use, as an open-source tool."
"It's like a centralized interface that allows us to increase the quality of our APIs."
"We find the product to be scalable."
"he initial deployment process is easy."
"The performance and reporting of this solution have been its most valuable features."
"It's an open-source tool and supports a lot of plugins and custom code, which allows integration with other tools like Azure and AWS."
"ReadyAPI automation can help us validate the functionality of most web services, allowing us to find out the exact number of defects before deployment to the user interface."
"It stores good reports, as in, improved reports if compared with the SoapUI. It also has in-built security. You just need to switch and check the security testing. My team has never used it, but I know ReadyAPI provides those facilities as well."
"It is a very good and handy product, there are so many features, and it is getting more popular day by day."
 

Cons

"The solution could use some sort of educational features to offer tips and hints to help users navigate it better. They should improve the manuals and help files."
"With JMeter, with banking encryption, we have struggled a lot; it's not as good as other paid tools that provide support and configuration capabilities that JMeter lacks."
"RegEx Extractor needs improvement. It's a headache for many people."
"In terms of setup, it could be nicer, to be honest. Sometimes, I get a little bit lost."
"The UI of the solution needs to be better. The UI takes up a lot of our bandwidth."
"When we are testing with too many threads then the solution hangs."
"We're like the solution to be more user-friendly."
"The UI has room for improvement."
"We need some time to understand and configure the solution."
"The solution’s interface could be improved."
"It is very slow sometimes. If they could improve its performance, it would be really great for the users."
"I want the solution to be able to monitor Apache Kafka activity as well."
"This is an area for improvement with the tool. We unnecessarily use JMeter for some website testing, which we would like to avoid by introducing this tool for API and load testing because it provides load testing features."
"The client-side scripting mostly isn't needed for performance testing, however, if implemented, it would enhance the tool."
"I'd not sure if they have the same level of documentation for performance and security testing."
"It is very slow sometimes."
 

Pricing and Cost Advice

"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."
"JMeter is open source and available free of charge."
"Since it is an open-source product, buying or paying for any license is unnecessary. One just needs to download it to be able to use it."
"Apache JMeter is an open-source solution, so it's free to use."
"This is an open-source solution, and there are no fees."
"The solution is open source with no user fees or licenses."
"We are using the free version, and if required, we can easily switch to the other version."
"JMeter is open source, so there are no licensing costs associated with it."
"We find the cost to be affordable."
"This solution operates on a licence basis and the usage and cost varies according to the use case. It is more expensive if you include access to the learning center. On average it costs approximately 800 Euros."
"ReadyAPI Performance’s pricing is reasonable."
