Performance testing tools are crucial for optimizing software, including websites. Why? Because performance directly affects user experience, conversions, and, ultimately, your bottom line. And this is something the market knows well.

In 2019, the global market size for software testing — which performance testing tools are a subset of — was more than $40 billion and growing rapidly. As a result, you can find plenty of performance testing tools to address different needs, use cases, and budgets.

In this article, we’ll look at some of the best performance testing tools, their features and benefits, and help you choose the most suitable ones for your needs.

Let’s begin!

What Is Software Performance Testing?

Performance testing is a type of software testing that helps you determine the performance of a software in terms of speed, response time, scalability, resource usage, and stability under a given workload.

The goal of performance testing is to identify all the performance bottlenecks in an application.

6 Common Types of Performance Testing

There are six major types of performance testing:

1. Load Testing

Load testing determines how the software performs with the increase in workload in a given time. This workload can be concurrent users, the number of transactions, software behavior, etc.

It aims at observing the response time, throughput rates, resource utilization, and more. By identifying any performance bottlenecks in these attributes, you can troubleshoot them before launching the application to ensure a better end-user experience.

Thanks to load testing, developers can understand how many concurrent users a software application can handle at a given time.

2. Endurance Testing

Also called soak testing, endurance testing evaluates the performance of the software over an extended period under a regular, fixed workload. In other words, it determines how long the software can endure a constant workload to provide long-term sustainability.

During this testing, test teams monitor KPIs like memory leaks, memory usage, memory shortages, and more. Endurance testing also analyzes response times and throughput after prolonged use to display whether these metrics are consistent or not.

3. Stress Testing

Stress testing measures software performance beyond the normal working parameters. It means the software is placed under higher traffic loads (more users, transactions, etc.) to help developers learn how well the software performs above its capacity limits expectedly.

The goal of this testing is to determine the software’s stability. It helps you understand the point at which the software fails and how it recovers from the failure. It strains hardware resources like CPU, memory, disk space, etc., to measure the application’s breaking point based on resource utilization.

Example: Companies perform stress testing before some major events like Black Friday to check the performance of their ecommerce applications.

4. Spike Testing

Spike testing is a type of stress testing that measures software performance under a significant and sudden ‘spike’ or increasing workload like simulated users. It tells you whether the software can handle that abrupt increase of workload repeatedly and rapidly.

5. Volume Testing

During the development phase, only a small amount of data is used to test code. Volume testing (also called ‘flood testing’) tests how efficient the software is when subjected to large volumes of data. It checks for data loss, system response time, data storage reliability, and more.

6. Scalability Testing

Scalability testing measures how effective the software is in handling an increasing amount of workload. The test will tell you its behavior when you scale up or down the performance attributes of the software.

You can perform scalability testing by adding data volume or users gradually while monitoring the software’s performance.

Benefits of Performance Testing

As per a report published in March 2019, Facebook suffered a catastrophic blackout and lost around $90 million in revenue. Similarly, App Store’s downtime resulted in $25 million in losses, said another report from March 2015.

Despite having robust IT infrastructure and security, these tech giants suffered huge losses. It proves how crucial performance testing is for your applications. It ensures all the features, functionalities, and systems perform optimally to offer a better user experience.

Now, let’s discuss some benefits of performance testing.

1. Measure the Software’s Speed, Stability, and Accuracy

Speed, stability, and accuracy are some of the significant attributes of software performance. Hence, testing your application for these aspects lets you monitor how the software behaves under pressure and provides you with crucial details on how it can handle scalability.

Looking at the test results, developers can learn what changes they must incorporate into the software to overcome the negative points and make it more efficient.

2. Validate the Software’s Basic Features

Your application’s success depends upon how strong its foundation is. Measuring the performance of fundamental features and functionalities of the software helps you make informed decisions and plan your business strategy on the software’s setup.

You can use your performance testing results in your research and development departments and pool your resources accordingly to enhance your software performance and product offering.

3. Identify Issues and Resolve Them

Performance testing will tell you the key issues that you can correct before launching your site or app. That means you can quickly resolve all the problems identified and concentrate on improving its technology instead of fighting the issues after release.

4. Enhance the Software’s Load and Optimization Capability

With performance testing, you can better handle volume and load capacity and optimize your software in such a way that helps the software withstand high numbers of concurrent users.  It will also detect the scalability issues that you can address as soon as possible and allow the testers to tailor capacity to handle high demands.

5. Improve the Code Quality and Software Functionality

When you can detect the issues in your software, you can eliminate them quickly. As a result, your developers can maintain quality code and improve the application’s functionality, delivering the expected speed, reliability, scalability, and stability.

6. Meet User Expectations

Your customers won’t like slow, laggy software that kills their time and annoys them. They expect it to load quickly — within 2 to 3 seconds — and work smoothly, without any confusion. The first impression of your software is crucial in deciding whether users will want to continue using it or hit the uninstall button.

Performance testing helps you meet the desired software attributes and keep your users happy to continue using your software, boosting your revenue.

Bonus Tip: Performance testing is best done just after you make the code available. It will help the developers get feedback in real-time to fix issues as early as possible.

The Performance Testing Process

The goal of performance testing is the same for every software, though the methodology can vary a bit. So, here’s what a typical performance testing process looks like:

  • Choosing the testing environment: First, select your test environment, performance testing tools, and production environment. Select appropriate software, hardware, network configuration, etc., to use for your test.
  • Identifying performance metrics: Next, identify software performance metrics such as response time, throughput, transactions, load time, and resource distribution like CPU, memory, and disk space.
  • Planning the test: Identify test scenarios covering user variability, target metrics, and test data. It will help you plan and design a few models of your performance tests.
  • Configuring the chosen test environment: Organize the elements of your test environment in addition to the performance testing tools you need for different test cases. For example, to test your website’s performance, performance testing tools such as Kinsta APM can help.
  • Implementing the test design: Create your performance test depending upon your test design, which will help your team stay on track during the entire testing process instead of getting confused.
  • Executing performance testing: Now, you can start the test. As it runs, monitor the trial and collect the resulting data so your developers can use it to improve the software performance.
  • Analyze, report, and retest: After you have the test results in hand, analyze the data and plan what you need to overcome the highlighted issues. Lastly, troubleshoot the problems and execute the performance testing again to track the improvements. Keep retesting until you troubleshoot all of the problems detected.

Now, let’s look at some of the best performance testing tools available on the market.

How to Choose  the Best Performance Testing Tool for Your Needs

As you saw, there are plenty of options available. To help you pick the best solution for your needs, we’ve compiled a list of essential aspects you might want to consider when evaluating options.

1. Ease of Use

The performance testing tools you use must be easy enough that they don’t cause your testers more problems than they solve. If your IT team is familiar with specific tools, you can ask them what those are and how they perform. It will cut down on time spent learning the new software.

Or you can go with a new but efficient tool, provided it’s got an effortless-to-use GUI, and you’ve found analysis plugins available for extensibility.

2. Available Test Environment

The performance testing tool you choose must access enough network and hardware resources to produce a sufficiently available performance testing environment. Most of the tools we’ve mentioned come equipped with a testing environment for you.

If it can’t generate a test environment to simulate an expected amount of network traffic properly, the tool might not be suitable to meet your company’s requirements.

3. Tool Efficiency

The efficiency of a performance testing tool depends on the number of virtual users it can accommodate currently to carry out the test on a single operating device.

The efficiency is more if it needs fewer devices and produces large-scale tests. For that, it must be proficient in generating an expected number of virtual users on the current hardware.

4. Scalability

A performance testing tool’s scalability depends upon the chosen protocol along with your test environment’s deployment configuration. To check the tool’s scalability, you can conduct a Proof of Concept test for your performance testing tool.

It’s best to perform a proof of concept test to validate whether a product or idea is feasible or not to move ahead. You’ll get valuable information during the testing phase, such as customer feedback, business analysis, competitor research, expected financials, marketing strategies, and more.

5. Protocol support

Different vendors offer different app protocols such as HTTPS, HTTP, SSH, FTP/STFP, etc. Choose the tool based on the nature of the app protocol you like to utilize.

If you have questions that the tool’s available documentation doesn’t answer, ask your vendor whether the tool supports the protocol or not, especially for complex protocols like Citrix.

6. License and Its Cost

Licensing can be a challenge with many performance testing tools. Commercial tools usually offer better protocol support but with certain restrictions. Review and be aware of the tool’s licensing before using it. And if it’s a paid tool, check their pricing, compare with others, and choose what falls within your budget with essential features.

7. Integration

Performance testing tools work extraordinarily well when integrating with other monitoring, diagnosis, defect management, and requirements management. It will help you learn the nature of metrics the tool can bring you concerning diagnostics and monitoring. Additionally, you’ll get an idea of how to track these tests and find defects easily.

For example, StormForge integrates seamlessly with cloud providers like AWS, GCP, IBM, etc.; monitoring tools like Prometheus, Datadog, Circonus, etc.; DevOps tools like Jenkins, Puppet, Rancher Labs, etc.

8. Extensibility and Adaptability

One performance testing tool won’t have all the capabilities you might need during the test. Hence, discover how flexible and extensible the tool is so you can integrate it with other 3rd-party tools and increase its functionalities.

For example, Apache JMeter is highly extensible and works with pluggable samplers, scriptable samples (e.g. Groovy), pluggable timers, data visualization addons, analysis plugins, and more.

9. Support

Find out the level of user support you can expect from the tool’s vendor. Generally, commercial vendors offer high-quality support through various channels of communication, documentation, and more.

If you go with open source software, check their community support, forums, active members, and so on.


Nobody likes waiting for a website or app to load. And when it does, they may consider other available options, resulting in you losing business. That’s why there’s a vast market need for faster websites and applications.

It’s crucial to do performance testing on your website or application to make sure they load as quickly and function as optimally as possible so your users can rely on them. By implementing the changes indicated necessary through your testing, you can achieve more conversions.

As we’ve shown, there are plenty of options available on the market for performance testing tools. Go for the ones you think will be best suited to testing your site or app’s requirements.
