They scale, but not how you'd like. Adding BW has a logarithmic
effect on latency reduction, but only within the tree of HTML
from a single source. I don't have statistics on how
long users stay at a source - that's client-side logging info,
whereas web servers (by nature) log server-side stuff only.
I would predict that they would scale to around BW = 7^3, or around
350x, and latency would reduce from 2.1 RTT's down to 0.2 RTTs avg
The real goal question is:
what is the min BW required to support interactive web access?
this depends on whether you support HTML/ASCII,
icons (small gifs), screen images (gifs), or
higher resolution stuff...
PS - the Lowlat pages now have the graph that describes this.
PPS - this seemed like a general enough question, I thought I'd share
the response with www-speed - I hope that's OK..
