Curious - if    anything it's more than 10 times, maybe as much as 20 
times.  I might expect a minimum TCP handshake's worth as a multiplier, 
but not a 20x increase in queries vs packets.

But, does that graph only show port 53 IP traffic, or might it be 
including something else (e.g. downloading of server logs) which is 
excluded from the "DNS Transport" graph ?
