This isn't a problem, just a curiosity. My ADSL Max connection is interleaved and always has been. In the past, when I've pinged a responsive UK site such as bbc.co.uk I got a value of around 40 ms. But now, if I ping bbc.co.uk I get a result averaging less than 30 ms, with some results as low as 25 ms. It's normally expected that interleaving will result in an increase in latency of 20-40 ms, so this seems unusually low. I don't know if this is relevant, but i see in my router's connection data the line:
Delay of latency path: 4.00 ms
but i don't know if this relates to interleaving.
It appears that this router, on this connection, delivers surprisingly low latency. It's an unlocked BT 2700HGV Business Hub. Can anyone shine any light on this?
