FWIW, I've done the calculations of the average time to find the key
for two cooperating and two non-cooperating keyservers. They serve out
keys at equal rates, but the rate increases with time.
== Fit to exponential growth starting 3/14/97
ave time for 2 cooperating keyservers 66.8 days.
ave time for 2 NONcooperating servers 68.7 days.
I'm pretty sure this result is correct, kind of amazing cooperation
only makes a difference of a couple days. This is because so many keys
are being checked near the end. I guess our 10% daily growth rate probably
can't be sustained to the end of the search, but maybe we'll be lucky
and get a good chunk of it.
== Fit to LINEAR growth over last 12 days
ave time for 2 cooperating keyservers 109 days. (from 3/14/97)
ave time for 2 NONcooperating servers 121 days. (from 3/14/97)
I guess a linear growth rate at the current rate is more practical.
Still, only a 12 days (on average) gain from cooperation.
So now I know when it doesn't pay to cooperate. My two kids have been
trying to teach me this by example for years!
