Network Latency Test
測試連接到全球主要服務的延遲時間
Frequently Asked Questions
What is network latency?
Latency is the time for data to travel from source to destination and back, measured in milliseconds.
How to reduce latency?
Use wired connection, choose closer servers, reduce hops, use CDN, or upgrade your router.
What is jitter?
Jitter is variation in latency over time. High jitter causes unstable connections in VoIP and gaming.
What is considered acceptable latency for video calls?
Video calls require latency under 150ms for smooth conversation. Above 300ms, noticeable delays make real-time conversation difficult. Under 50ms is ideal for professional conferencing.
How does geographic distance affect network latency?
Light travels through fiber at roughly 200,000 km/s, adding about 1ms per 100km of cable. A cross-Atlantic connection (6,000km) has a minimum physical latency of ~30ms one way.
