Best website load testing services

Iryne Somera Developer Tips, Tricks & Resources

Website load testing services determine how websites deal with online traffic. Too often, people equate it with performance testing. However, load testing is just a type of website performance testing. Other types of performance testing include endurance testing, volume testing, scalability testing, spike testing, and stress testing. 

In website deployment, it is common that transactions may fail and systems crash. It is due to concurrent demands on the website and adjustment over resources. Also, there might be untested codes that trigger failure. These situations arise, but developers fail to realize that it is associated with load design and testing. 

Most often, developers conduct load testing as part of the project finale. It is only at the end of the development that developers focus on load implementation. It is a risky and often incorrect approach as it misses out on the benefits of load testing at the start of the development. 

Also, website load performance failures are due to additional problems like page speed, resource exhaustion, buffer overflows, timeouts, and inconsistent behavior. Thus, website development needs website load testing services at the very start. 

Let’s talk more about load testing.

What is Load Testing?

Load testing is a type of software testing method. It tests software (websites, web apps) with multiple user simulation. It answers how many users can access your website at once. Also, how will your website function under multiple users or a sudden increase in volume? 

Load testing offers vast performance benefits, such as: 

  • Decreases the possibility of downtime
  • Enhances the deployment quality of an application
  • Enables developers to find performance bottlenecks
  • Assures customer satisfaction
  • Provides tangible statistics to website developers

Load testing is an essential feature of software quality assurance. An ineffective load testing procedure may result in financial loss and project delays. Hence, it is valuable since it ensures the website’s efficiency related to customer usage.

There are several ways to have an efficient load testing procedure. You can opt for the basic load testing tools available. Or, you can go after advanced Application Performance Management (APM) solutions like Retrace

Retrace helps eliminate additional costs of fixing problems by running an effective performance testing procedure. It proactively improves your website performance. You can explore its Sandbox or start your FREE trial today. 

Top 10 Website Load Testing Services

Building a website is a significant element of any business today.  Everybody wants to have a fantastic-looking website brimming with valuable information. However, there is always a constant struggle when it comes to performance. 

When you have a slow website, chances are you lose customers and revenue. Thus, it is vital to establish your load testing procedures and determine what website load testing services to use. 

Just like all types of testing, load testing has been around for a long time. Developers either choose traditional standard load testing methods such as protocol-based website testing. However, as websites are getting complex, the demand for modern and automated load testing techniques is prevalent.

Remember, protocol-based website load testing simulates virtual users. It works by generating many specific protocol requests. Then, it measures website performance based on request-response behavior.  

For example, HTTP servers generate user load for the website and performance parameters. Such parameters include response time, response delay, computation time, and network delay.  It then measures these parameters under peak conditions. 

Let’s examine different website load testing services based on their features and protocols used.

Make the most out of Load Testing 

Websites should be able to handle the amount of traffic it receives. Website load testing services are great at overcoming this performance issue. However, not every organization thinks about this before they start the website development process. 

Mostly, companies choose the best website developers thinking that their sole expertise helps build a fast website. But, the focus must not rely on human resources alone. Yes, a good web developer can design and adjust the design into something that can handle the online traffic. Yet, there are still instances that a website receives sudden traffic spikes and needs tools.

Website monitoring is essential to business operation. Although companies can run several performance tests, not all have the capability to run tests on their own. It is where you can hire companies to check your website regularly.

There are many options for website load testing. The top requirement is choosing a provider that has experience is very important, like how Retrace from Stackify stay ahead of the game with some companies. With APM like Retrace, the testing is granular. It involves more than just clicking on different features around the website. It covers total application performance management.
