As website traffic increases, it is important to ensure that your website can handle the load. One way to achieve this is through load testing, a process that helps identify bottlenecks and other performance issues.
What is a Load Testing Tool?
A load testing tool is a software application designed to simulate real-world user traffic and assess the performance and scalability of a website, web application, or API under various load conditions.
Load testing tools generate virtual user traffic, mimicking the behavior of multiple users accessing the system simultaneously, to evaluate its performance, identify bottlenecks, and ensure that it can handle the expected load without degradation in performance.
