Dave, for last few days I have been measuring Comcast's download and  
upload speeds here in Wash DC area.

The following pattern seems to suggest that Comcast is not optimizing  
peering opportunities for max speed for its customers, at least here  
in DC.

Following stats come from Speedeasy.net; measured in No Va suburbs of  
Wash DC served by Comcast 'high speed' internet, a label that's an  
obvious oxymoron

Wondering whether Comcast is favoring its own network to carry traffic  
on East Coast, and not doing much for traffic coming from Dallas or  
Chicago
