I used to see ~10ms to the aggregation router with ADSL on Fastpath. I generally see ~25ms now, with ADSL2+ on Interleaved profile. It reflects a different approach to connection speed between my old ISP (AT&T; limiting the MaxSync rate by tier) and my new ISP (Sonic.net; letting the connection run near the maximum sustainable rate).

I don't think that is an awful result; but I probably could get Fastpath if I requested that they throttle back the MaxSync rate to raise the SNR to 10-11dB. I just don't need lower latency enough to bother.
