技术说明
Each sample is a fetch request to a tiny same-origin endpoint with cache disabled. The page measures performance.now() from request start to response completion. That includes DNS, TCP/TLS reuse, server processing, and the return trip, so it is an application-level round-trip time, not an ICMP ping.
Jitter is the average absolute difference between consecutive samples. Results depend on your connection, Wi-Fi, server load, and the browser. A single run is a snapshot, not a guarantee of network quality.
故障排除
All samples fail
Check your connection and reload the page. A proxy, firewall, or offline state can block the test endpoint.
Latency is much higher than in a game
Application requests include HTTP and server processing. Game latency also depends on the game server and route.
Results are unstable
Wi-Fi interference, background traffic, and bufferbloat cause variation. Test with a wired connection or at a quieter time.
The first sample is slower
Connection setup and TLS handshake can add time to the first request. Later samples usually settle down.
