What is Network Latency?
Network latency is the time it takes for data to travel from one point to another across a network. It represents the delay between sending a request and receiving a response, measured in milliseconds (ms). Lower latency means faster response times and better network performance.
Latency is affected by various factors including physical distance, network congestion, routing efficiency, and server processing time. Understanding and monitoring latency is crucial for optimizing network performance and user experience.
Latency Categories
Excellent (< 50ms)
IdealPerfect for gaming, real-time applications, and video calls. Virtually no noticeable delay.
Good (50-100ms)
GreatExcellent for most applications including web browsing, streaming, and online gaming.
Fair (100-200ms)
AcceptableAcceptable for web browsing and streaming, but may cause slight delays in gaming and real-time apps.
Poor (> 200ms)
SlowNoticeable delays in most applications. May cause buffering, lag, and poor user experience.

Frequently Asked Questions
What is network latency?
Network latency is the time it takes for data to travel from one point to another across a network. It is measured in milliseconds (ms) and represents the delay between sending a request and receiving a response.
What is a good latency?
Generally, latency under 50ms is considered excellent, 50-100ms is good, 100-200ms is fair, and anything over 200ms may cause noticeable delays. For gaming, latency under 50ms is ideal, while for web browsing, under 100ms is acceptable.
Why can't browsers do real ping tests?
Browsers cannot send ICMP ping packets due to security restrictions. Instead, this tool uses HTTP requests to measure response time, which is more relevant for web applications and provides similar latency information.
