Using performance testing tools, developers and IT teams can catch performance issues early and adjust the application and its compute and network resources to optimize performance and eliminate bottlenecks. Performance testing tools can determine an application’s speed and stability under various workloads to help devs and sysadmins make sure it meets requirements.

Performance testing helps dev teams and system and network engineers evaluate how well an application works and what it can do. It can determine how much a program can handle before it crashes and identifies any instability in the program.

Often, developers will have a set of requirements they need to meet, and performance testing can help determine whether or not the dev team has been successful. For example, an e-commerce application may need to be able to handle hundreds or thousands of users at once. Performance testing tools could simulate a large number of browsers accessing the application at once and see how it performs, looking at load speed, stability, and resource utilization to see if any changes are needed. The technology is sometimes called application performance testing (APM).

IT and dev teams looking for software performance testing tools should look for at least the following features.

If IT teams need to know how many users an application can handle before it crashes, they need a performance testing tool that offers real or emulated browsers. This allows developers and IT teams to simulate a number of users accessing the application at once to see how it holds up. Additionally, they can see how the software looks and acts on different browsers (Chrome, Firefox, Safari, etc.) without having to actually download all of the browsers on their device.

Without this feature, an engineer would have to use a variety of devices and browsers to run the same tests, which could significantly delay the entire project.

Automated testing features help reduce the workload on human system engineers, which are already hard to come by. The software engineer growth rate is only about 8 percent, meaning there will soon be more open roles than there are engineers to fill them. And the gap is only growing as tech workers become overworked and burn out. With automated testing, devs and sysadmins can avoid tedious testing tasks, only jumping in to fix issues that the system finds or to run specialized tests.

Artificial intelligence (AI) can also lessen the burden on dev and systems engineers by identifying dependencies in an application and prioritizing issues. This prevents engineers from adjusting one part of an application without addressing functions of the application that are dependent on that piece. AI can also predict system failures before they happen, allowing sysadmins to avoid problems and address the issues sooner.

The following list contains some of the best performance testing tools, chosen for their high user reviews and helpful features.

Radview WebLOAD provides performance and load testing with the ability to simulate a large number of virtual users at once. It’s available on the cloud in a fully-managed version or on-premises for self-hosting. The dashboards and reports are flexible and customizable, allowing developers to get the insights they need. WebLOAD has three subscription tiers, but the actual pricing information is not available on the website.

LoadNinja provides an easy-to-use interface for performance testing, complete with instant playback and real browsers to help ensure accuracy. The system makes it easy to create web and API load tests, and it provides real-time feedback on performance issues. Users can also automate user interface and API testing, so they can focus on more complex issues. There are four pricing tiers available starting at $99/month, with greater savings provided for purchasing a full year at once.

LoadView is a cloud-based performance testing platform that provides real browsers for increased accuracy. It works for web pages, web applications, and APIs, and the system is fully-managed by LoadView, so sysadmins can focus on testing instead of maintenance. Users can design multiple test scenarios or have LoadView handle it through the professional services option. Companies can purchase the system monthly, yearly, or on an on-demand basis.

Micro Focus LoadRunner allows globally distributed teams to easily collaborate on performance testing. It’s available for both cloud and on-premises environments, with the cloud-based tool offering the ability to simulate over 5 million virtual users. Users can run multiple tests at the same time, and it offers a large number of integrations, including Kubernetes, Docker Swarm, Selenium, and AppDynamics. Pricing information is not available on the website.

NeoLoad from Tricentis is an enterprise performance testing tool that helps organizations simplify and scale their software development processes. It works well for APIs and web services as well as full applications. The cloud-based platform integrates easily with any cloud development platform and offers an automated approach to reduce some of the burden on sysadmins. Pricing information is not available on the website.

Rational Performance Tester from IBM allows systems and network administrators to test their products earlier and more frequently during the development process. It can identify the causes of slowdowns or bottlenecks in the software and integrates easily with other IBM products for full visibility into the development environment. Users can also create test scripts without programming, making testing easier. Interested organizations will have to contact IBM for pricing information.

SmartMeter.io is a performance testing tool that offers an embedded browser, making it easy for users to create and run test scenarios. Live test monitoring allows users to see how the program responds to changes in real-time, but there are also detailed reports available after the test has concluded. The system also automatically backs up test scripts and results of tests that users have already run. There are four subscription tiers available with prices starting at $39/month. However, yearly subscribers get the first two months free.

Apache JMeter is an open-source performance testing tool that can simulate heavy user loads and provides its own testing IDE. It works with a large variety of protocol types, including FTP, web, TCP, and Java Objects. Users can analyze results even while offline and record tests from their browser or native applications. Because Apache JMeter is open-source, it is free to use and download, although users can sponsor or donate to the program to aid in development.

Performance testing tools help IT and dev teams catch issues early in the development process, meaning they won’t have as many customer complaints down the line. Additionally, because problems are easier to fix the earlier engineers catch them, they’ll improve the ROI on their product.

To find the right performance testing tool, organizations need to choose a platform that includes its own IDE or integrates with their dev team’s chosen IDE. Additionally, they’ll want to be able to run a variety of different tests and simulate large loads to see how the application holds up. Finally, businesses should consider performance testing tools with automated testing and artificial intelligence to reduce the workload on already overburdened employees.
