How to Load Test Your Application

Frequently used terms in this article: server: a single server where our application is running (or) a setup with multiple servers where our application is running. client: a server that is used for firing/sending requests to our application. Why Load testing? Load testing is the process of putting load (user requests) and then checking the response of your application(under test). It is performed to check the system’s behavior under defined load and the peak load conditions.

Why Load testing?

Load testing is the process of putting load (user requests) and then checking the response of your application(under test). It is performed to check the system’s behavior under defined load and the peak load conditions.

This testing usually helps in identifying -

  • The maximum operating capacity of an application.
  • Determine whether the current infrastructure is sufficient to run the application.
  • Sustainability of application for peak user load.
  • Number of concurrent users that an application can support, and scalability to allow more users to access it.

What problems does it help us solve?

Prevent the slow performance or even shutdown of the website during a high load.

Long load time

The load test tells you how long it takes the pages to load at different traffic levels. You will get metrics on website speed during normal, peak, and overwhelming traffic load.

Poor response time

Response time is a time a system takes to respond to a user’s requests. Load testing will help you to establish what causes delays in response time and optimize your system accordingly.

Poor scalability

Scalability is the capacity of the app to perform different tasks at the same time. As the number of your users grows, your app must be capable of processing a larger number of requests rapidly, without slowing down the overall performance. Load testing helps you determine whether your application scales when a load grows.
