I switched from Orcon wholesale to Telecom VDSL Ultra last month (location Beach Haven, about 2km from the exchange and 400m from the cabinet).  The changeover was 3 weeks ago.  I already had a master splitter and have been running my ADSL on a dedicated cat 5 line for years so internal wiring isn't a problem.  

ADSL speeds have been 13-14 MBit down and 1 up since we changed to wholesale after cabinetisation, although there have been slow spots of about 6-7 (remember when that was fantastically fast?).

Initial VDSL speeds were 13.7 down and 9.7 up with a latency of around 35, which was ok.  I've left it a few weeks but it has never wavered (points for consistency at least).  At least the latency has dropped down to 5ms which is great.

I logged into the modem and found the following stats:

Bearers generic info DS US
Payload rate [Kbps]: 37522 10351
Attenuation [dB]:       12.4   26.4
Margins [dB]:             12.3   18.4
Output power [dBm]:   13.5   -0.4

Number of bearers: 1
Bearer 0                  DS   US
INP [DMT symbols]:  0.00 0.00
Delay [ms]:             0.00 0.00 
Depth []:                1     0.00
R:                          0     0

From my reading on the subject this is now on the optimum DLM profile and I would have expected download speeds of about twice what I'm receiving, if not more.  Is my understanding correct on this and if so, just how long does it take?  Should I be hassling tech support about this yet?
