Difference Between JMeter and LoadRunner

To examine an application’s stability, speed, efficiency, and sizing, performance testing is required. In performance testing, the analytics of an application is obtained through various load testing measures. Software like JMeter and LoadRunner is used for this purpose. Both these tools help users find bugs and threats in the software applications.

JMeter vs LoadRunner

The difference between JMeter and LoadRunner is that JMeter is free software while LoadRunner is costly. Users have to pay to get LoadRunner. The buyers of LoadRunner are usually enterprises to check their applications. While many developers use JMeter to test software performance as it can detect small bugs and threats.

JMeter vs LoadRunner

JMeter is an Apache software that is an ideal choice for web application testing. Users can measure load strength as well as test performance. Users can get extensions and customize the software according to their needs. It doesn’t support JavaScript. It is not as proficient as paid tools. It comes with benefits like high portability, extensibility, simple installation, limitless load generation, and easy integration with plug-ins.

LoadRunner is a complex software that can identify performance bugs in web applications. It can find performance gaps. Users can test ERP software and Web 2.0 technologies. The individual units of the application can be tested. It can also forecast expenses for upgradation. It supports a wide range of applications, enables mobile testing and cloud testing, and gives an accurate analysis.

What is JMeter?

JMeter is a load testing software developed by Apache Foundation. It is used for web application tests, functional tests, and similar tests. It analyzes the functionality of the software. The efficiency of each software can be determined using JMeter. There are multiple benefits that one can reap using JMeter as it is free and has an open-source license.

It has a user-friendly setup. It is a Java desktop application. The load testing results can be viewed in the formats like tables, files, charts, or trees. It can be installed easily, and users can advance it according to their needs as it provides extensive support. Database performance can also be evaluated using this software.

It has a graphical interface that enables the use of Swing graphical API and assures that the software can perform in any environment. Many protocols are accepted by JMeter like HTTPS, LDAP, SOAP, etc. it has a multi-threading framework.

Many users send requests to a specific server and then provide the statistics regarding functionality. This simple mechanism is used in JMeter. Unit tests are also available in JMeter. Spike testing and performance testing are the primary aspects of this software. It has access to offline test result support. It can engage multiple users through simulation to create a heavy load. Thus, gives an accurate account of load testing.

It has the record and playback option that helps in creating scripts with ease. Users can find many tutorials and support online from the JMeter community. So even beginners can find adequate information. Although scripting needs some advanced knowledge, users can still use the software.

What is LoadRunner?

LoadRunner is software developed by Micro Focus that enables software testing. It can identify system efficiency through performance testing. It supports multiple protocols and several software platforms. The mechanism of working of LoadRunner is recording and replaying user activities and creating a heavy load on the server to be tested.

The user activities are scripted, and then such scripts are run to create virtual users. The virtual users generate traffic, and thus the heavy load is created. After the test, the users can get the analytics as a file that can be opened through the Microfocus analysis tool. It gives the load testing result. The final test result is obtained in the form of pdf, HTML, Excel, or other formats. 

The LoadRunner software has many components. Load generators, agent, virtual user generator, controllers, and analysis. The scripts are generated by the Virtual User Generator. It is in the programming language. Virtual loads are generated according to the need in load generators. The controller manages the load test. It organizes the workload modeling.

The agent enables communication with the Load generator and controller. Finally, the analysis provides the results of the load testing. The performance bugs can be detected using the report. LoadRunner, with its simple interface, gives a user-friendly experience. There is no need for physical users as virtual users can provide sufficient real load on the server.

Also, the requirement of hardware is limited. All the virtual users can be handled single-handedly. The auto-correlation feature is an advantage to the users. It facilitates cloud performance testing. It can easily integrate with APM tools.

Main Differences Between JMeter and LoadRunner

  1. JMeter is free software, while LoadRunner is a paid resource.
  2. The user interface in JMeter is not as efficient as LoadRunner’s. LoadRunner has more features that give a more advanced performance. But JMeter has only limited features.
  3. JMeter can handle unlimited loads, but there is a limit for load generation in LoadRunner.
  4. Users can customize JMeter according to their needs. LoadRunner does not allow that. The existing features can only be used.
  5. Apache is the owner of JMeter. The LoadRunner was developed by Micro Focus, and HP owns it.
  6. JMeter can support Windows, Mac, and Linux. While LoadRunner cannot support Linux.
