How to test node latency and real speed correctly

Two different metrics

• Latency (ping): the round-trip time in milliseconds — affects how fast pages open and how a game feels.
• Speed: how many MB per second it moves — affects downloads and video quality.

Testing in v2rayN

Select a node: Test latency (Tcping) measures the handshake; Test real delay actually hits the target and is closer to real feel; Speed test downloads a file to gauge bandwidth (it uses data — mind your quota on a paid plan).

Reading the numbers

• Latency timeout / -1: node is down, skip it.
• Low latency but pages still slow: bandwidth may be throttled — confirm with a speed test.
• After a batch test, sort by latency and try the top few by hand.
