Most of the ADSL installations I've seen in SBC 13 state area had interleaving turned on, which significantly increases latency. I suspect that's why many cable MSOs in the same territory have "cable is better for gaming" marketing campaigns running all the time.So the latency you see on an ADSL line is dependent on how the carrier set up the DSLAM.
Interleaving is good because it reduces bit error rate on the line. Would be good though if the carrier let the customer change the properties of the line to optimize for different things, high snr target/no interleaving for low bw/low BER/low latency applications, low snr target/interleaving for file transfers.
