多区域延迟 / 测速

Node speed test — measure download bandwidth and latency to nodes in several regions (Hong Kong / Singapore / Japan / US / Europe) to assess your line / VPN quality.

What this tool measures

Your browser downloads a chunk of data from each region's node and converts the elapsed time into download bandwidth (Mbps); it also takes the minimum round-trip latency (ms) over several zero-byte requests. It is a multi-region measurement of download direction + latency.

How to read the results

• low latency + high bandwidth → a good line for that region;
• unusually high latency or collapsed bandwidth in a region → a detoured / congested / throttled line;
• comparing several regions reveals quality differences between your VPN landing or relay nodes.

Notes

• it measures the download direction only, not upload;
• each payload is capped (to bound bandwidth use), so bandwidth is an order-of-magnitude estimate, not a peak benchmark;
• results depend on your local network, node load, and momentary congestion — run it a few times for a trend.

FAQ

Why do the numbers differ from other speed-test sites?

Test-point location, method (single- vs multi-threaded), and payload size all differ, so numbers are not directly comparable. This tool is about multi-region comparison — which line is better for you — not the highest score.
