This is interesting. This may sound like a naive question. But if queuing delays are so insignificant in comparison to other fixed delay components then what does it say about the usefulness of all the extensive techniques for queue management and congestion control (including TCP congestion control, RED and so forth) in the context of today's backbone networks?
Latency is cumulative. Knocking a little time off Part A will still act to shorten total time, regardless of the time occupied by Part B Queuing behaviors are also significant when you are suffering congestion, apart from the delay factors -- Eric A.
