13 best tools for performance testing

In the fast-paced age we live in, slow or crumbling websites and applications often mean a loss of revenue for the business. You prevent that by performance testing, so let’s take a look at the best tools for it.

Performance testing is the process of running a technical analysis on a web or mobile app to identify bugs and usability issues. This can include evaluating if an application responds to user inputs as expected, how quickly it loads and renders data, whether it’s able to scale up or down as needed, etc. Here are the primary performance testing types:

  • Load testing is an effective way to evaluate how a web or mobile app will behave in real-life situations. It simulates the kind of load that can be put on the system while it is being used by users.
  • Stress testing is similar to load analysis, but it focuses more on how well your system will perform under high loads, which may not be normal.
  • Endurance testing refers to how long your software can handle extreme amounts of traffic and how fast it recovers from any issues that arise during this time.
  • Spike testing focuses on how quickly your web page responds once a spike occurs. For example, if you are hosting multiple content all on one page, spike testing will help you determine whether or not this content will stay up during spikes in traffic.
  • Volume testing refers to how many users are accessing your website at once and what happens when they try to access it going over load capacity and/or bandwidth limitations.
  • Scalability testing is focused on the ability of an application or service to handle increased demand without experiencing degradation in performance.

Different types of performance testing tools are available for doing these technical analyses. Some focus on specific areas like UI speed or network throughput, while others can be used for broader tasks like stress or load testing. 

Before we look at the best tools for performance testing, let’s consider how you make test cases for them. Manual test generation has long been the primary way. The latest AI tech, however, allows you to cover a lot of similar scenarios in no time. We recommend aqua’s AI Copilot, as it leverages GPT to generate tests while knowing the context from your entire test suite.

Apache JMeter

Apache JMeter

One of the best tools for performance testing out there, Apache JMeter was created to analyse load balancers, but it’s now used for testing servers, websites, and applications of all kinds. It is one of the best tools for performance testing because it can simulate multiple users and applications as well as load different types of data such as databases, XML, file systems, email, etc.

JMeter also comes with an Administration Console (JMX). You can use this console to trigger actions, collect and analyse software data, log events, and much more.

When it comes to the management of web and app performance tests and other test types, finding the right tool is critical. Take the aqua test management tool for instance. With aqua’s native integration with JMeter, you can create, track, and record automated test cases on JMeter in real-time. It also lets you add and connect any software to your testing via REST API with a simple setup and automated bulk inputs.

LoadNinja

LoadNinja has an easy-to-use interface with drag-and-drop functionality, real-time monitoring capabilities, graphical data visualisation capabilities, and rich reporting options. 

This performance testing tool also has integration capabilities with other tools such as SiteScope and Jira so you can use their reporting data without having these QA management software installed.

You can also use LoadNinja to analyse software performance across multiple environments from development to QA to production. You can even create batch files with LoadNinja which will execute automatically every time you launch it!

PFLB

PFLB

PFLB is a load testing platform where you can test your web and mobile apps, as well as gRPC and APIs. It is extremely helpful for teams who want to ensure that their product can handle all the action before releasing or scaling up. With PFLB, you will have complete control over your app’s capacity, eliminating the hassle of crashes or those pesky 503 errors. This platform also allows you to save a significant amount of money on cloud computing and compare your software with the competition.

One of PFLB’s standout features is Automatic Test Plan Generation. By linking your Google Analytics account, you can create accurate load profiles that are based on real user data from your website.

Other useful features include support for high geo-distributed loads, custom scripting capabilities, seamless integration with CI/CD processes, and integration with Grafana.

LoadRunner

loadrunner

LoadRunner is a powerful tool for functionality analysis and load generation. The tool can be used to simulate user interactions and load application servers with different types of traffic, such as HTTP or FTP.  The results will show you how fast your pages load and how many users are accessing your site. It also gives you an insight into the type of traffic your site is receiving at any given time.

LoadRunner supports many different browsers and operating systems, which makes it easy to use with your own applications. LoadRunner also has a built-in scripting language that allows you to create your own custom scripts.

LoadView

loadview

LoadView is another popular alternative you can use for your website or application. In comparison to LoadRunner, this tool has more advanced features, but it is not as easy to use as LoadRunner. You need to install the Java plugin before using this tool, which may not be an option for everyone. 

This program also does not have a built-in scripting language like other tools do, so you will have to write your scripts if you want them in this program.

NeoLoad

neoload

NeoLoad is similar to LoadRunner in many ways because both programs are used for analysing web pages and applications in browsers and operating systems from different vendors (such as Internet Explorer, Firefox, Safari, and Opera). However, NeoLoad offers some additional features that make it stand out from the rest. 

The main benefit of using NeoLoad over LoadRunner is that it’s one of the few open-source tools for performance testing (which means anyone can look at its code) so you can easily modify it if there is something that doesn’t work how you want it to work. It is also pretty easy to integrate with a bug tracker via REST API. Also, NeoLoad is free for up to five servers so there are no hidden costs or hidden fees involved here either!

RedLine13

FAQ
What tool is used for performance testing?

JMeter and LoadNinja are two of the most popular performance testing tools. JMeter is a preferred option for heavy lifting, while (still highly capable) LoadNinja is appreciated for its simple user interface and visualisation features. 

What is Performance Testing?

Performance testing is a set of quality assurance activities validating that a solution performs well at different levels of load. It is extremely important for B2C solutions that can see significant fluctuations in demand. 

What are the different types of performance tests?

The main types are load testing (real-life performance), stress testing (high loads), endurance testing (pushing for the breaking point), spike testing (load fluctuations), volume testing (bandwidth), and scalability testing (automated or manual increase/decrease in resources).

What is KPI in performance testing?

KPIs are the measurable results of your performance testing, e.g. how many requests per second can the system handle or how long it takes the user to get a response in the worst-case scenario.
