Speed Test With Jitter [extra Quality] ●

Jitter is defined as the statistical variance of packet inter-arrival times. If packets are sent at perfectly regular intervals (e.g., every 10 ms) but arrive at intervals of 8 ms, 12 ms, 9 ms, 11 ms, the variation is jitter. When jitter exceeds the buffer capacity of an application, packets are either discarded or delayed, causing perceptible degradation.
