Apache JMeter vs Gatling Tool- Load Testing Part 1
It is really hard to decide which tool to use- Apache JMeter or Gatling Tool. Both of them are Load testing tools. Whenever we consider which tool to use, there are so many questions that come to mind.
There is a never-ending list of questions that come to our mind. In this blog post, we try to cater a few questions and will try to help you to decide which tool is appropriate for which project environment.
We will be presenting a comparison between JMeter and Gatling Tool on the basis of the following categories:
We will see with the tool outperform in which category. In this blog post we will be discussing the first 5 categories:
1. Project History: This section shed some light on the historical information about 2 tools,
JMeter was first released 21 years ago in 1998. This is a pure Java project with more than 20 versions released till now. JMeter is an open-source project released under Apache 2.0 License. Till now, 33 people contributed to the project. So, in a way, we can say that Apache JMeter is a mature project.
If we talk about the Gatling tool, it was first released in 2011, so it is just 8 years old. This is a comparatively new tool compared to JMeter. Gatling is a Scala-based load testing tool that supports full Functional Programming. It is also an open-source tool registered under the Apache 2.0 License. More than 60 people contributed to this project to date.
Both JMeter and Gatling are maintained regularly. But we can say, JMeter is a clear winner. JMeter has a codebase of 500k lines of code, which is far more than Gatling with 50k lines of code. This is probably due to the use of Scala in the Gatling tool, which is a concise language if we compare it with Java. Moreover, JMeter is a more mature project with more number of contributors as compared to the Gatling tool.
2. Documentation: The match between JMeter and Gatling becomes more clear with discussion on documentation.
JMeter's documentation is very detailed, where each feature of the tool is detailed with every possible setting.
Gatling Documentation is very concise and clear document.
Both the tools covers:
Both the tools have a community on StackOverflow. Verdict for this comparison is that
both tools are equally good.
3. Development: This section will give an overview on which programming language is used for developing the 2 tools.
Apache JMeter is developed using Java Programming Language. This is an
a open-source tool. However, OpenHub shows that it also contains HTML and XML.
Gatling is a load testing tool developed using the Scala programming language. Since Scala supports Functional Programming aspects, it automatically makes Gatling having functional programming aspects.
Here we can say Gatling is a winner as it is open-source plus the development language is Scala, which is concise and adds Functional Programming aspects to the feature list of Gatling.
4. Built-in Facilities: In this comparison, we will see out of the 2 tools which are
is easy and light to execute.
JMeter supports execution in 3 different modes:
Gatling, on the other hand, supports only 1 mode.
It does not support UI Result Listeners, without which it is very difficult to analyze the results. As a graphical view of results helps in better analysis.
As you can see, JMeter is the winner in this area, as it offers the developers with the choice to either go with GUI mode, Server mode or command line mode. Whereas in Gatling developer have only 1 choice command line mode.
5. Setup: Both the tool has prerequisites Java JRE pre-installed on the machine.
The only difference between the 2 tools is that JMeter comes with a GUI Executable.
Again, it is your choice which tool is best suited to your requirement.
Till now, we can see in some categories JMeter is a winner and in some there is a draw between the two. In the next blog, we will present a comparison on the basis of the remaining five categories.
