In my experience, exactly the same.

Will the DSM/DLM over the next few days change the latency or will it just affect the speed?

It usually changes latency before speed.

That's colloquially called a JDSU. Your modem will also give you the exact same information.

You'd be surprised. I've seen people with 140 meg attainable on a 80 meg sync still get interleaving switched on.

Quite the opposite, best not leave it a few days. DLM ignores any restarts during the first few days because it knows people are likely to be tweaking/moving/restarting the equipment more than usual.

Mine's gotten fairly similar after 10 months of increasing crosstalk, though I managed to get it to resync during a power cut when pretty much every electronic device in a mile (except the cabinet and my modem, both of which have backup power) was off so zero interference or crosstalk. So far it's stayed up for 2 weeks at full sync despite the SNRM dropping to 3dB. Still, stable at 80Mb sync aint bad for someone who was predicted 53Mb. But the 110Mb attainable without crosstalk gives me hope for 200Mb when 30a + vectoring come out.

Define "long". Attainable rates of ~80-100 are typical at around 300-400m line length assuming little interference, though in my case I'm 90m from the cab and have a line that behaves like a 400m because VM is so crap that takeup on FTTC is huge.

VM's cable is 20 year old copper and can do 5-10Gbps...
