As for performance, lots of others will probably volunteer tips and 
techniques. In my experience, properly written and tuned applications will 
show only minor speed differences. I have seen several open-source apps 
that "support postgres" but are not well tested on it. Query optimization 
can cause orders of magnitude performance differences. It sounds maybe 
dspam is in this bucket?

I made a little chart about these about a year ago:

If speed is what you need, and data integrity / safety is not, then MySQL 
may be a good choice. (Aggregate statistics tables and other such 
calculated denormalizations).

IMHO, if all you need is dpsam running *now*, then I'd say MySQL might be 
good choice. If you ever need to run a DB application where data integrity 
is mission critical, then postgres is the top of my list.
