What is Performance Testing? What are the Top Performance Testing Tools?

The way your prospect buyers and potential users interact with your software application matters a lot more than you think. The application is the representation of your whole business; therefore, it must be highly efficient to manage any stressing conditions as well as the workload.

Generally, IT hubs want their products to be error-free and successful. But Performance testing delivers more than that and help in the creating of a distinguished product in the end.

Achieving positive feedback and satisfactory responses from the end user isn’t the only goal of Performance testing.

Let’s suppose, your newly released application become successful in little or no time. It would be quite obvious that all the fame and success was gained by the huge number of users installing and functioning it. But just a few months later, the app collapses. Why? Because it could not manage the cluster of users, thus the workload and eventually crashed.

Feels like a nightmare? Yes, it does!

Consequently, developing and releasing are the most hectic steps for the completion of any product, and just so you know, this where the bulk of performance assessment takes place.

A responsible Performance Tester verifies the critical website’s loading speed as well as its content delivery.  More importantly, they look to battle those tough situations to get that app in the stream when it gets stacked with hundreds of thousands of users.

Being able to fight any such situation is the real victory and this is why it’s crucial to know the value and worth of Performance Testing.

The Value of Performance Testing

Before moving ahead, let’s talk about the load time and the worth of performance. All you need to understand is performance is the magic wand to bring your users a great user experience.

There are many tools available to measure the load time, but first things first, every newbie tester must know the performance metrics that rule out the app experience.

So, here we are, discussing some of the convincing reasons that claim the value of following are some of the important metrics that claim the value of performance testing:

  • If your webpage or app is load under 100 milliseconds only, it is considered highly instantaneous and this can only be achieved by performance testing.
  • While a delay of 100 milliseconds to 300 milliseconds is perceptible.
  • 1-second delay is just the beginning for your user to stay uninterrupted
  • Users want or expect a website to load within 2 seconds
  • It is tested that after 3 seconds, about 40% of audiences will leave your site
  • 10 seconds is the end of your user’s limit to keep its attention on that website.

Following these metrics, app developers must not forget the importance of performance testers that work to meet the expected user behaviors and end up providing the best load time to the websites.

What are the Objectives of Performance Testing?

Pre-defining the performance metrics are highly recommended before heading towards other testing practices. So, generally, testers are responsible for:

Application Responsiveness: A responsive app is a treat for your users. It assures how fast the app responses after a user has made a request or query. App’s responsiveness is highly anticipated at both user and server ends.

Resource Management/Measurement: This performance metric helps testers in defining parameters in resource utilization. This way they can measure the rate of utilization of every system’s resource accumulated in the testing process, say per transaction or per operation. Mostly, these system resources are databases, Network I/O, Disk I/O, CPU, Memory, etc.

Application Throughput: Testers do the quantitative measure of the request being made at a specific time period. TPS (Transaction per second) is the most used technique to do the requested measurement. The transactions can be the regular ATM-linked transactions, number of simultaneous users, etc.

Workload: It is the ability of an app to manage the cluster of users at a given time. While load testing, testers simulate the concurrent users in order to estimate the workload more efficiently by putting in a self-imagined think time. Simulation of concurrent users saves the app from crashing in the future.  Workload testing gives testers the idea of app’ response to real-world situations accordingly.

Applicable Test Case Creation: Designing applicable test cases is another important step of performance testing. In this, testers make sure that every test case is tested on several servers as well as simulated environments. The test results indicate the performance of an application in the future, which includes consistency, stability, scalability, degradation tolerance, and so on.
