When working with people in the tech industry, whether it’s on the website or an application, you may hear the phrase round-trip to the server. This refers to how much time it takes to begin a request and for that request to go to the server perform some processing and return with a response
It is a metric used to measure how good the user experience is. The aim should be to minimise this time, as much as possible, to provide a more responsive user experience to anyone using the product.
