Well, I have two answers to that, and they may differ from what you expect :-).
1. On our systems, at Afilias, we never run slon processes on
database servers. We instead run all the slons centrally on an
application server.
2. If the choice is between master and slave, I'd be somewhat
inclined to run both slons on the "master" server, as...
- Life tends to be simpler if they both run on one server, as
you can more readily manage processes on one host, and as
log files will naturally be on one server.
- It is essential that a slon be kept running against the master
node, as if it is not, for a period of time, then when it
is restarted, that entire period of time will be treated as
One Big Long SYNC, and having such a huge SYNC is likely to
turn out badly :-(.

"... The book [CLtL1] is about 400 pages of 8.5" by 11" Dover output.
Apparently the publisher and typesetter decided that this made the
lines too wide for easy reading, so they will use a 6" by 9" format.
This will make the shape of the book approximately cubical. Now,
there are 26 chapters counting the index, and a Rubik's cube has 26
exterior cubies. I'll let you individually extrapolate and fantasize
from there." -- GLS
