I like that you are asking the question. But I hate to guess at
which
is better though. The weakest benchmark data point is better than
the
strongest guess. Too often I have taken my best guess and been
wrong.
In this case I would guess the opposite would be more efficient, that
the one spamc-spamd connection per message would be more efficient
than the many mysql queries per message, which is why I bring this
up.
Well that's something to consider. I had hoped when I subscribed to
this list to ask this question that I'd find people, possibly SA
developers on it, who had benchmarked the options I presented for
decision and could give me some definitive answers based on this,
but it
appears that this isn't the case. Instead I've found several people
of
good will who don't seem to know a whole lot more about SA than I do,
but have given me some good points to think about.
Do you have any idea where I might inquire to get advice from people
with more precise knowledge?
This is the best place. Its not a common setup so I don't doubt that
anyone really knows the correct answer.
One data point I'll add is that spamc has a compress mode that might
be useful (spamc -z). Also, it would take a little work on your end
but you can also pass in --headers to further reduce the spamc/spamc
traffic. Check out the spamc man page for more info.
One other thing related to MySQL. I've never personally done it but
I'm certain there are ways you could use MySQL proxy or perhaps even
federated tables to manage this sort of thing. MySQL proxy has lots
of different functions, I'm sure compression is either one of them or
at least something that can be easily bolted on.
