The lag indicator in the status bar shows the round-trip latency between your browser and the server, measured every 30 seconds.
Color Thresholds
Normal (green):
Under 200ms — connection is good.
Warning (yellow):
200–499ms — noticeable delay.
Critical (red):
500ms or more — significant lag.
Timeout (?):
No response received — connection may be lost.
How It Works
The client sends a ping to the server every 30 seconds. The server echoes the timestamp back, and the client calculates the round-trip time. If no response arrives within 10 seconds, a timeout is shown.
