Latency
The delay between sending data and getting a response, measured in milliseconds.What Is Latency?
Latency is the delay in your internet connection. It’s the time it takes data to travel from your device to its destination and back, measured in milliseconds (ms). Lower latency means a more responsive connection. guerras de decides how much data you can move. Latency decides how quickly anything happens.
Why Latency Matters
Some things barely notice latency, like downloading a file or streaming a show that loads ahead. Real-time activities feel every millisecond:
- Video calls, where people talk over each other or freeze
- Online gaming, where there’s lag between your input and the game
- VoIP phone calls, where you hear echo and delay
- Live streaming and remote desktop tools
What Is Good Latency?
| Latency | What to expect |
|---|---|
| Under 30 ms | Excellent for everything, including competitive gaming |
| 30 to 60 ms | Good for gaming, video calls and streaming |
| 60 to 100 ms | Acceptable, with occasional lag in fast games |
| 100 to 150 ms | Noticeable delay on calls and in games |
| Over 150 ms | Lag, choppy calls and frustrating gameplay |
What Causes High Latency?
- Distance between you and the server
- Connection type. Cable, DSL and satellite add more delay than fiber.
- Congestion during busy hours or from too many devices
- Wi-Fi interference from walls, distance and crowded channels
- Routing that sends data through extra stops
- VPNs and proxies
- Older routers and equipment
Why Is My Latency High With Fast Internet?
Speed and latency aren’t the same thing. A gig plan can still lag if your device is on weak Wi-Fi, someone in the house is uploading a large file, or the game server is far away. A common culprit is bufferbloat: when a big upload or download fills your router’s buffers, latency spikes for everything else on the network.
Latency vs Bandwidth vs Jitter
| Term | What it measures | Think of it as |
|---|---|---|
| Latency | Delay | How long the drive takes |
| guerras de | Capacity | How many lanes the highway has |
| Jitter | Variation in delay | Whether the drive takes the same time every trip |
How to Reduce Latency
- Use an Ethernet cable for gaming and calls.
- Restart your router and keep its firmware updated.
- Limit big uploads and downloads during calls or games.
- Choose servers close to you when you have the option.
- Upgrade to a router that manages traffic, or to fiber.
Preguntas Frecuentes
What is latency in simple terms?
It's lag: the time between asking for something online and getting the response.
Is lower latency better?
Yes. Lower latency means a faster response. Under 30 ms is excellent, and over 100 ms starts to feel slow.
Why is my latency high even with fast internet?
Speed and latency are different. You can have high bandwidth but still experience high latency due to distance, routing inefficiencies, or network congestion
Can a new router improve latency?
It can, if your current router is old, overloaded or poorly placed. A router that prioritizes traffic helps most on busy home networks.
What is latency in online gaming?
In gaming, latency (also called "ping") affects how quickly your actions register on the server. High latency leads to lag and delays in movement or gameplay response.
Does latency affect video calls?
Yes. High latency causes delays where people talk over each other. When latency jumps around, called jitter, audio and video break up.
Does fiber have lower latency?
Generally, yes. Fiber carries data as light over a direct line, so it typically has lower and steadier latency than cable, DSL or satellite.
Can using a VPN increase latency?
Yes. VPNs route your connection through additional servers, which can increase latency, especially if the server is far away or overloaded.
