JMeter vs LoadRunner

The transition from the Center of Excellence with open-source load testing is inspiring most designers to use software development tools such as JMeter instead of LoadRunner. Comparing the options is a reasonable thing to select the best development environment for your company. This JMeter vs LoadRunner comparative article will assist you in determining which one best suits your needs.

In this blog post we are going to discuss the jmeter, loadrunner and key comparison between jmeter and loadrunner.

Let's start our JMeter vs LoadRunner comparison with an overview of both software testing tools.

Performance is becoming an unavoidable factor in today's world, particularly for web and mobile applications, where user strength is extremely high for each application. JMeter is a popular tool for performing performance tests. 

What is Jmeter?

Apache JMeter is a software testing tool that is used to analyze and measure the performance of various software services and products. It is an open source Java software that is used for testing Web Applications or FTP applications.

It's being used to execute web application performance testing, load testing, and functional testing. JMeter can also simulate a high load on a server by adding a large number of virtual concurrent users to the web server.

Why do we need jmeter?

For web application testing, Apache Jmeter is the ideal performance testing tool. It provides users with a variety of performance testing and integration capabilities. As a result, you must not only evaluate the functional capabilities of web services and apps, but also assess load strength and platform compatibility.

Besides that, software testers can transfer testing tools for different servers and browsers. Simultaneously, Apache Jmeter provides robust features for running customized tests on protocols such as HTTPS and HTTP for web, SOAP, POP3, JMS, and SMTP. As a consequence, users can make sure that your web applications are fast and free of errors.

What is loadrunner?

Micro Focus' LoadRunner seems to be a software testing tool. It's being used to test applications, as well as to measure system behavior and performance under load. It can simulate thousands of users using application software at the same time. It aids in the analysis and prevention of application performance issues.

LoadRunner has the following features:

  • Lower hardware and software costs by accurately predicting system capacity.
  • It quickly and accurately pinpoints the root cause of application performance problems.
  • It has effective tool utilization tracking Browser-based access to global test resources and optimal use of load generator farms.

Why do we need loadrunner?

Loadrunner would then collect information from three network elements like database systems and web servers during testing. Following data collection, the implementation evaluates the gathered data in depth and provides useful insight into why the implementation is harassing in a specific way. As a result, users can easily find out the cause of application defects.

Because Loadrunner includes cloud-based testing features, users can execute speedy, flexible, and reasonable load testing from multiple locations. You can also use the cloud to differ the website burden and recreate the needs of business applications.

Jmeter vs loadrunner: Key parameters comparison:

LoadRunner has a strong market position, and Apache JMeter is quickly catching up, faster than any other performance tool available today. Now, I'll assist you in deciding between these two testing tools by comparing them on the following criteria:

  • Availability
  • Load Generation Capacity
  • Execution
  • Analysis Report
  • Open-source & Community support
  • Scripting
  • Building test-scenarios
  • Elements

Apache JMeter is a free and open source software testing tool that can be easily downloaded and used to run any test.
LoadRunner is an impressive purchase of software testing equipment. It recently released free trial versions, but they cannot be downloaded and used.

Load Generation Capacity:

  • JMeter has an infinite capacity for load generation.
  • LoadRunner has a greater capability for load generation.


  • JMeter makes execution simpler. Install Java, download JMeter, and upload the JMeter script file.
  • When compared to JMeter, execution is more complicated. It creates a separate thread for each user.

Analysis Report:

  • The results are simple to understand for less experienced engineers while also allowing for in-depth analysis for more experienced testers.
  • The data is in raw format, which HP Analysis parser to generate various graphs.

Open-source & Community support:

  • Jmeter has a thriving community that assists users who run into issues or problems.
  • Loadrunner is owned by a large corporation, so the number of users is limited.


  • In JMeter, users could indeed run a full load test without knowing a single line of code.
  • LoadRunner, but on the other hand, necessitates scripting expertise.

Building test-scenarios:

  • JMeter does not require you to include any beginning or ending transaction elements.
  • LoadRunner is more complicated because it requires the management of multiple agents.


  • When compared to LoadRunner, adding elements in JMeter is simple.
  • In LoadRunner, configuring each element is more difficult.

  • It is completely free to use.
  • Extraction of data in popular response formats such as JSON, XML, HTML, and so on.
  • High-level configuration is accomplished through the use of a command-line interface.
  • Recording tests for native applications and browsers
  • It is simple to incorporate with plug-ins and third-party tools.
  • Visualization and data analysis plug-ins are widely available.
  • Java-specification
  • Simple to set up
  • Extremely adaptable
  • Easily transportable
  • Capacity to generate unlimited amounts of load
  • Excellent community of support

Jmeter disadvantages:

Although the Apache Jmeter has many advantages, it also has a few drawbacks, which are listed below:

  • Because it does not support JavaScript, it does not support AJAX requests by extension.
  • When used in GUI mode, the application's memory consumption can be quite high.
  • High memory consumption causes errors for a large number of users after a certain threshold is reached.
  • Advanced models that use JavaScript or dynamic content, such as CSRF tokens, can be difficult to test.
  • Less capable than paid performance testing tools like Loadrunner
Loadrunner advantages and disadvantages:
