one registry site per 45 nodes sounds a bit (a lot) short to me. I'm
running a rgyd on a dn3000 (8MB) that is the gateway to my ring and I
see the effects now and then.

I seem to remember the docs saying something like "use as many as you
need".  I'd guess that something like one rgyd per 25 nodes or so would
be a bit more reasonable (though I'd like to hear what rule-of-thumb
Apollo has too...especially regarding what system to use and how much
memory).

Based on what I've seen, the amount of memory and the number of other
processes you have makes a big difference (for example, if you run "at"
or "cron:, you'll see lots more effect than if you have a rgyd.).
