For example, improving latency by as little as 0.1 latency is the number one reason consumers abandon mobile sites. Fine-tuning the service-level indicators that make up quality gates will improve with the help of upcoming features. Organizations can feel the impact of even a minor roadblock in the user experience.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. 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). Two-way latency is often called round-trip time (RTT).
