Looks can sometimes be deceiving. ;-) I've seen Comcast drop packets
left and right, but show 8Mbs/2Mbs on speed test sites. Other times
I've seen the opposite, zero PL but extremely high latency (seconds,
double digits!)... all the while non-dynamic web pages (probably
cached upstream) loaded just fine.
Look, I've always been a big fan of Comcast.... but at this point I
suspect they have just about over-engineered their network.
