Jitter

Jitter is a measurement of variation in consecutive latency test results, and is represented as an absolute value. Ideally, one would want a jitter result as close to zero as possible.​

What is Jitter?

For example, a latency test is started by using the ping command to a server on the internet with the following results:

  • First latency test is 30ms | No jitter can be calculated with only one latency result.
  • Second latency test is 35ms | 35ms - 30ms = 5ms of jitter
  • Third latency test is 32 | 32ms - 35ms = 3ms of jitter
  • Fourth latency test is 50ms | 50ms - 32ms = 18ms of jitter

Jitter is considered to be bad when it is more than 20% of your average latency. Since latency tests require the use of bandwidth, a sudden burst in download or upload usage can cause a larger latency result and, in turn, affect your jitter results. The use of Wi-Fi will also have a large impact on latency and jitter because it is affected by interference and objects blocking line of sight to the Wi-Fi device.
