What Does Latency Mean for You?
Online Gaming
Under 20ms is ideal for competitive gaming. 20–50ms is good. Above 100ms causes noticeable lag and input delay. Distance to the game server is the biggest factor.
Video Calls
Calls are comfortable under 150ms. Above 300ms you'll notice awkward pauses and people talking over each other. Use a wired connection to reduce latency.
Web Browsing
General browsing is comfortable with latencies under 200ms. CDN-hosted sites are faster because content is served from servers geographically closer to you.
Live Streaming
Streaming to Twitch or YouTube is primarily limited by upload bandwidth, but latency under 100ms helps keep the encoder's buffer stable and reduces dropped frames.
Why Does Distance Matter?
Data travels through fibre optic cables at roughly two-thirds the speed of light. Even at that speed, a round trip from New York to Tokyo covers ~22,000 km — introducing at least 73ms of unavoidable physical latency before any network overhead. This is why CDNs (Content Delivery Networks) place servers around the world: to bring data closer to users and minimise latency.
