Be interesting to hear what the group thinks ... but one aspect of this
might be because you went from fixed latency to variable latency. ATM with
fixed windows, to a bursty PPP connection.
I would guess that the ping measurements you have taken are based on
averages ... and so the burstiness of your new connection may cause the
average delay times to vary some.
Too much to write in one email ... but as part of your migration plan I
would hope that you have considered and or deployed QoS ... this might also
have something to do with the ping times being different now.
Not sure this helped much ... but, I HTH,
