Yet, not all packets are not created equal - in size.  So, 42, 150 byte
packets queued is not the same as 42, 1500 byte packets.  However, 10,
1500 byte packets is the same as 100, 150 byte packets.

Had you said something like MB and delay should have the same effect I
would have agreed with you :)
