Can Selenium be used for performance testing?

Selenium is primarily designed for functional testing, not performance testing. It excels in automating web applications for testing functionalities, user interactions, and browser behavior. However, when it comes to Selenium automation testing, it’s not ideal for performance or load testing because it doesn’t handle multiple virtual users or measure system resource usage under load. For performance testing, tools like Apache JMeter, LoadRunner, or Gatling are more suitable. These tools are specifically designed to simulate high traffic and measure how well a system performs under stress. While Selenium can contribute to load testing in very limited scenarios, it's not built for this purpose.
