Apache JMeter vs Cavisson NetStorm comparison

Apache JMeter is an open-source Java application that tests load and functional behavior and performance in applications. Created initially to test web applications, it has expanded its functionality to test other functions. For instance, you can test a server to see how efficiently it works and how many user requests can be handled simultaneously.

You can use JMeter to test functional performance and regression tests on different technologies. This Java desktop application has an easy-to-use graphical interface which uses the Swing graphical API. You can run JMeter on any environment that accepts a Java virtual machine, such as Windows, Linux, and Mac.

What protocols does JMeter support?

• Web - HTTP, HTTPS
• Web services - SOAP/XML-RPC
• Email service - POP3, IMAP, SMTP
• FTP service
• Database via JDBC drivers
• LDAP
• Native commands or shell scripts
• TCP
• Java objects

How does JMeter work?

JMeter sends requests to a target server by simulating a group of user requests. Then it collects and calculates statistics on the performance of the target. This target can be a server or an application.

You can test the performance of static resources, such as JavaScript or HTML, and dynamic resources, such as JSP, Servlets, and AJAX. It is also helpful to determine how many concurrent users your website can handle.

There are two main tests you can carry out with JMeter: load test and stress test. The load test models expected usage of a server by simulating multiple users accessing the web server simultaneously. The stress testing aims to find the maximum load capacity of the server or application.

Apache JMeter Key Features

• JMeter enables fast test plan recording, building, and debugging via a featured test IDE (integrated development environment).
• Command-line mode allows carrying out load tests from any OS compatible with Java.
• JMeter can extract data from most popular response formats, such as HTML, JSON, XML.
• JMeter is entirely portable.
• A multithreading framework allows you to simultaneously test multiple samplings and separate thread groups.
• Thanks to the caching feature, you can conduct offline analysis or replay test results.

Apache JMeter Benefits

• As open-source software, it is freely available and continuously improved.
• The setup is user-friendly, and no installation is needed.
• The GUI (graphic user interface) is intuitive and easy to use.
• You can write your own tests and use the visualization plugins to extend the testing.
• It is a platform-agnostic tool. For example, JMeter can work with Linux by clicking on the JMeter shell script. On Windows, you can call up JMeter by starting the jmeter.bat file.
• Since the test plans are stored in XML format, you can generate a test plan using any text editor.
• You can simulate a heavy load on a server, a group of servers, a network, or an object. Use JMeter to test an application or server's strength and performance under different load types.

The JMeter extensible core has numerous benefits:

• Unlimited testing capabilities via pluggable samplers.
• You can choose multiple load statistics with pluggable timers.
• Visualization plugins and data analysis enable customization.
• Continuous integration via third-party open-source libraries (Maven, Gradle, and Jenkins).

Reviews from Real Users

Stephen B., I.T. Architect, Analyst, and Developer at an educational organization, says, "The scripting ability is most valuable. It is easy to use. There is a UI, and you can go in there and figure those things out. After you've got a good set of tests, you basically have a scripted document that you can grab and execute in a pipeline. It is pretty quick to set up, and you can scale it and version control it."

"I like the fact that JMeter integrates well with other tools," adds the Founder and Principal Consultant at a tech services company.

A Quality Engineering Delivery Leader at a financial services firm says, “The performance of the solution is excellent. They have designed the product so that it is very easy to configure. You can basically do anything you like with the product. It's not very restrictive. We like the fact that the technology is open-source.”

Cavisson NetStorm is a powerful load testing solution that is designed to enable application developers to greatly improve the way their applications function. It employs advanced software that enables it to perform many different tasks. This flexibility gives administrators the ability to test their applications in the way that best meets their needs. Cavisson NetStorm offers users the ability to scale their testing environments. These aspects of the solution are only a couple of the reasons that this platform is the load testing tool of choice of several fortune 100 corporations.

Cavisson NetStorm Benefits

Some of the ways that organizations can benefit by deploying Cavisson NetStorm include:

• Cost-effectiveness. Cavisson NetStorm is a cost-effective solution that is well worth the price. The wealth of features and the sort of tasks that Cavisson NetStorm can be employed to accomplish make it possible for organizations to create products that perform at peak effectiveness. It starts with a free trial that becomes a quote-based price.

• Ease of use. Cavisson NetStorm is intuitive to use so that organizations do not need to formally train employees in its use. Its design saves developers time and makes organizations more productive.

• High level of stability. Cavisson NetStorm users don’t need to be concerned that it will crash or suffer other performance-related issues when it handles large test loads. It is extremely stable and can easily handle heavy workloads without suffering from an outage. Administrators can let the solution do its work while maintaining peace of mind.

• Gain deep insights into application behaviors. Administrators can leverage Cavisson NetStorm’s monitoring features to observe many different aspects of the application testing process. One such aspect is the way that the applications behave when they are exposed to certain environment types. Users can obtain in-depth insights as the tests run that will help them understand how their applications function in specific situations.

Cavisson NetStorm Features

Some of the many useful features Cavisson NetStorm has to offer include:

• Diagnostic alert capabilities. Cavisson NetStorm allows users to create diagnostic warnings prior to the commencement of testing. These alerts warn users when deviations from their pre-set testing parameters are taking place. If the application is behaving in a way that is abnormal, these alerts will make sure that administrators are aware of what is going on.

• Test result reporting tools. Cavisson NetStorm offers administrators the ability to create test result reports that can clearly lay out information belonging to a number of different categories. It has prefabricated reporting templates that enable users to illustrate the kinds of information that is most important to them.

• Testing dashboards. Cavisson NetStorm comes with a central dashboard that can visually lay out various testing metrics for administrators to view. It also includes dashboards that enable users to view technical or business-related data exclusively.

• Performance analysis. Cavisson NetStorm can analyze how specific components of the application are impacting its overall performance. If there is any portion that is negatively impacting its performance, Cavisson NetStorm’s analytical tools will find them so that administrators can remedy the problem.
