To be more specific: slowness can be introduced as your digital connection traverses your PC, the local wifi/wired connection, the local ISP, the Tier 1 or Tier 2 provider, or the CDN that provides the hardware which hosts the web server running the application. Your PC sends out what is called a “SYN” packet to the destination’s IP address.

A TCP port is a unique number assigned to specific services and applications that run on a server. It serves as an endpoint for communication between a client and the server, allowing different communication processes over a network. TCP ports operate at the transport layer of the Internet Protocol Suite. What is a TCP Port?
