Introducing the queue mechanism in Laravel

We will implement a simple use case in order to shed light on the asynchronous aspects and how much a queuing mechanism can improve the user experience for the end users of our web application.

For every request, a time-consuming task will be executed. To simulate the time-consuming task, we will call sleep() to last 3 seconds. The sleep() function, which suspends execution for a certain number of seconds, is intended to simulate the execution of a task that may take some time to implement. In a real case, the sleep() function is replaced with complex business logic that could take a certain amount of time to complete.
