Apart from the setup point, the real issues for Slony performance all
lie in the amount of data churn.  Inserts are slightly cheaper than
updates or deletes.  100 active users doesn't sound like a lot to me,
provided you give yourself an additional 20% or so I/O ceiling for the
Slony overhead (which is not usually that high, but you don't want
spikes to get in your way).
