Oh now this is a surprise :
Ping statistics for 87.237.39.90:
Packets: Sent = 1178, Received = 1178, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 9ms, Maximum = 74ms, Average = 11ms
That is with 2 netflix HD streams running, hence the "spikes" (can't really call them that).
Now I had around 25ms latency with ADSL, I was expecting to have +/-5ms on that with VDSL, likely more as it needs more error correction. 11ms average seems like quite a drop.
Probably just "first on the cabinet" stats....
