My data point:
I'm working from home. My computer is connected through company VPN, over wifi
to Comcast.
Comcast speed test says 18mS.
I use VNC and Webex with voice and video through the computer.
VNC response time and voice delay is not noticeable.
Regards,
Jakob.

From: Adam Thompson <athomp...@merlin.mb.ca>
I’m looking for a practical guide – i.e. specifically NOT an academic paper,
thanks anyway – to predicting the effect of increased (or decreased) latency on
my user’s applications.
Specifically, I want to estimate how much improvement there will be in
{bandwidth, application XYZ responsiveness, protocol ABC goodput, whatever} if
I decrease the RTT between the user and the server by 10msec, or by 20msec, or
by 40msec.
My googling has come up with lots of research articles discussing theoretical
frameworks for figuring this out, but nothing concrete in terms of a calculator
or even a rule-of-thumb.
Ultimately, this goes into MY calculator – we have the usual north-american
duopoly on last-mile consumer internet here; I’m connected directly to only one
of the two. There’s a cost $X to improve connectivity so I’m peered with both,
how do I tell if it will be worthwhile?
Anyone got anything at all that might help me?
Thanks in advance,
-Adam
