I would say that if there was an effect on the connection, people would surely have pointed it out by now given how terrible those graphs are.

It's reasonable to put it forward as a theory ... but it doesn't become fact, just because no one is in a position to disprove it.
But anyway, thinking about it: "priority" would only explain the symptoms when under heavy load - most of the TBB graphs I've seen show the same effects in the dead of night when the connection is not otherwise 'in use'. It would be a strange algorithm that purposefully delayed ICMP echoes, when there was no other work to do.
Here is an overview of the data from my tests. This is a
real application, suffering a
real degradation in its performance.
My line speed is 30Mbps/2, but with the old Draytek in circuit, the downstream is more like 10Mbps - yet latency improved dramatically.
If these UDP packets had been from a game, or a VOIP application, they would presumably have been affected in exactly the same way.
