Latency
Latency (Up/Down): Latency is the amount of
time it takes for a packet to go from the source
to the endpoint or from the endpoint to the
source (in milliseconds). Latency is calculated
by averaging the thousands of latencies
measured during each interval. The one-way
latency measurements are actually round trip
measurements, divided by two.
Peak Latency: The highest measured latency.
The Current column shows Peak Latency from
the last test interval, and Max shows the
highest latency measured during the entire test.
Limit: This is the Latency Threshold from the
Performance app's setting.
