Why Performance Testing For Web & Mobile Apps?

When was the last time you got stuck on a website due to a heavy traffic load? Does it not seem like a common issue while filing your taxes or checking your examination results online?

Website performance issues and crashes have been disrupting the online space. According to The Guardian, Victoria’s Pfizer vaccination program was bombarded with tons of requests. This resulted in website crashes and millions were unable to reach the call center.

Tons of instances emphasize the need for Performance Testing. Performance Testing helps to check the behavior of an application or a website in several situations. A system can work perfectly fine with a particular number of users and requests but might crash during peak traffic and millions of requests. There are different types of performance tests that help simulate various possible environments and scenarios that can understand the behavior of the users and applications.

With the increasing competition in the digital space and the ever-changing marketplace, Performance Testing is crucial for enterprises. These tests ensure the speed, performance, stability, and dependability of the application.

Performance Testing does not always detect and display the defects of an application or a website. The main objective of conducting performance testing is to ensure that the application platform performs as expected irrespective of the traffic load, bandwidth availability, and network surge.

So conducting these tests is critical for ensuring the stability of the website.
An effective performance testing strategy is necessary for highlighting the performance issues and is done by following the industry-defined benchmarks to ensure that the application behaves stably. Automation of performance tests also adds value to the application testing process. There are several things you might miss out on if you do not conduct Performance Testing. Let’s take a closer look at what you would be missing out on.

Why Conduct Performance Testing?

Engage Your Customers With Improved Website Speed

A lousy website never draws a good audience. Performance testing enables the teams to analyze the performance and speed of the website. With the basic bandwidth and connectivity access, your users will have access to faster loading websites. Faster loading websites keep them engaged.

Faster Websites Generate More Revenue

For businesses directly connected with the customers, faster websites generate more revenue. Applications such as banking, online grocery, eCommerce, and other portals provide a secure gateway to the customers. Due to popularity, there is better traction and increased visits. Increased visits may increase the chances of increased loads and website crashes. Performance testing can analyze the performance and stability of such applications.

Frees The App From All Glitches

Performance Testing ensures that the application performs the way it is built. Different types of Performance Testing approaches detect performance flaws, issues, and stability of the application and resolve the risks that handicap the application in a real-world scenario.

Increase The Robustness of The App

Businesses need to ensure that their applications remain sturdy even during the most critical times. Issues like network surges, cyber-attacks, online threats, performance flaws, and other problems are just a few to mention. Performance testing with different tools improves the sturdiness of the application to strive in the marketplace.

Improves Scalability

With the ever-evolving market, enterprises go for dynamic applications that are scalable and upgradable in real-time. Performance testing detects the possible vulnerabilities in an app and identifies the pain points to increase the scalability. Analyzing the data and statistics from the test executions help the QA teams identify the possible issues.

Identifies The DB & API Related Issues

Different types of Performance Tests such as load testing, spike testing, and a few more enable the team to evaluate the behavior of the application. These tests also check if the server responds to the user with data within a stipulated time gap. These tests further help to examine the behavior and performance of the API under heavy loads.

In the above point, we highlighted load testing, spike testing. Let’s check out the types of Performance Tests.

Performance Testing Types

Load Testing

This is the simplest form of performance testing that evaluates the performance of a system under a specific load. This type of testing measures the critical transactions and load on the database and application server of the business.

Stress Testing

Stress Testing finds the highest capacity of the system and determines how the system works when the current load goes up beyond the expected limit.

Soak Testing

Also called endurance testing, Soak testing determines the system parameters under the continuous expected load. The main point behind conducting this test is to discover the system performance under sustained load conditions.

Capacity Testing

Capacity testing is more targeted at testing whether the application or the software can handle the amount of traffic and requests that it was built to handle. Using this test, developers can check the number of users the system can handle without breaking down.

Spike Testing

This test is performed when there is an abrupt increase in the number of users by a very large amount. The main point behind conducting this test is to find out whether the system can sustain load spikes.


Investing in Performance Testing is extremely important for the success of businesses and organizations. To ensure the best speed, high performance, and seamless experience, it is necessary to set clear objectives while selecting the software testing tools, technologies, and environment to conduct performance testing.
