How to Choose the Right Load Testing Tool

An in-depth look into load testing tools will reveal a plethora of options available to you. The varieties are practically endless and include free load testing tools, paid performance testing tools, and “freemium” programs. It’s easy to get overwhelmed and confused. With limited information available on each of these load testing tools, it can be a hassle to figure out which serves best according to your load testing needs.

In this article we streamline the process for you by compiling information on the varying facets of each tool, thereby giving you the precise information you need to turn your curiosities into solid plans. We attempt to relay some of the benefits and pitfalls of using these differing avenues, so you may be able to make a better decision. We also go over different scenarios one may encounter while testing and displaying the better parts of each of these tools.

By using this resource and internalizing the information here, you can quickly gain a foundational knowledge of the working mechanisms of each tool and hence, you will be able to make a sound decision, avoiding any common traps or frustrations. If you’re still confused, our team will assist you with any additional queries that may come to you, and you can always schedule a one-on-one Loadview demo to speak with an expert.

Let’s dive into the details.

Open-source vs. Paid Load Testing Tools: Which Is Right for You?

Of the options available, some carry a premium price, others are free. As the saying goes: you get what you pay for. A basic definition of each of these terms will lead you to make a sound decision.

Open-source load testing tools do not come with an initial investment because they are usually free. Furthermore, the user can manipulate the code used and fit it according to their needs. However, to use open-source load testing tools, the user may have to invest in hardware to run it on their servers. It may also cause frustration because, as they are open-source, these tools come without paid support to answer questions you might have.

The premium you pay for paid load testing tools usually comes with advantages. The difference between paid load testing tools and free load testing tools lies in the cost you’d be paying for all the extra tools you might need for testing. Therefore, free load testing tools may not be free, considering the costs involved in setting up testing. Free load testing tools also come with the heavy burden of creating only ideal scenarios, whereas paying that extra bit of money with paid load testing tools may turn out to be beneficial because of their ability to access real-world scenarios.

The ideal situation would be to find performance testing tools that come fitted with the ability to do some load testing as well. Some of these paid load testing programs have an umbrella organization under which they run, such as LoadView that comes under Dotcom-Monitor, which provides umbrella performance testing tools. Finding such a program, you not only empower yourself with the ability to perform load tests, but also with data-driven insights into your website’s performance.

Your decision on whether to invest in paid load testing tools or free load testing tools should come with the awareness of your own needs. If you have a complicated website that needs highly specific maneuvering, then you should go for the free options. But if you want a more general type of test, then there’s no harm in paying for load testing tools.

Performance Testing Tools: Is Open-source Software Worth the Hassle?

Open-source software may sound appealing at first because of a lack of initial investment, but once you start to work around it and apply it to your system, you may find that the lack of initial investment turned on its head and got you to spend more than you would’ve for a paid load testing tool.

Open-source load testing tools are difficult to set up. Besides, since they’re user-generated software, their user interface might not be ideal or fit to use. This does have the possibility of the user spending more time than is needed to set up and run the program. Additionally, specific hardware that you might need to run these programs may not be available to you, and you’d have to spend money to acquire them. In the case that you have the hardware needed to run open-source load testing tools, you may find that it’s not compatible with the version of the software you’re trying to run. The lack of support offered or available may be another avenue where you might consider investing in paid load testing tools.

There’s another aspect to open-source load testing tools that’s often overlooked; since they’re open-source and the code is user generated, they may serve to infringe upon the software you already have. In such a case, a limited warranty is available for your help, and open-source load testing tools might become a liability.

Many costs are associated with open-source load testing tools including setup, installation, maintenance, and support. All this comes in addition to needing to familiarize yourself with the language of the software so that you may be able to work it yourself or to train others in doing so.

This leads to the conclusion that paid load testing tools are pricier up front but can save you from a lot of costs associated with free load testing tools in the long run. This, of course, you’d get in addition to a user-friendly experience, real-world scenarios, and a full support team.
