I am still waiting for someone to help with this question.  Using a
controller interface, when I issue a GETINFO ns/id/* or GETINFO desc/id/*
command where does the response data come from?  Does it just come out of
the cloud from one of the directory authorities?  Does it get read from the
local cached* file(s)?  Does it get calculated dynamically in real time?

I have recently been doing some timings of the controller interface, and
find that on average I can get a response to one of these GETINFO commands
in less than 0.06 seconds, and sometimes in as little as 0.0001 seconds.
However there are times when it takes up to 20+ seconds to get this same
data.  I am struggling to understand what might be going on here...
