Every time you load a website, there are a series of requests being made to the servers. Every request will have a response and each server will have a set number of concurrent requests it can handle. The more requests you have, the more requests your server will have to deal with, and the longer it will take to respond.
These requests can be hard to track and most often than not the number of requests fluctuates up and down especially if you are working with any third party services. With a simple setup, you can track the overall number of requests, load time, responses, and much more.
