Typical additional latency for CGN?

[Tom Limoncelli <tal () whatexit org>]

Have there been studies on how much latency CGN adds to a typical
internet user?   I'd also be interested in anecdotes.

I've seen theoretical predictions but by now we should have
measurements from early-world deployments.

Thanks,
Tom
