Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server).

You’ve probably heard things like: “HTTP/3 is much faster than HTTP/2 when there is packet loss”, or “HTTP/3 connections have less latency and take less time to set up”, and probably “HTTP/3 can send data more quickly and can send more resources in parallel”. We will discuss these features in more depth later in this article.
