Just for comparison's sake it would be interesting to see a curve for
mysql/myisam.  Mysql's claim to speed is mostly based on measurements
taken with myisam tables, but I think that doesn't hold up very well
under concurrent load.

        I'm doing that now. Here is what I wrote in the report :

Using prepared statements (important), Postgres beats MyISAM on "simple selects" as they say, as well as complex selects, even with 1 thread.
        
MyISAM caused massive data corruption : posts and topics disappear, storage engine errors pop off, random thrashed rows appear in the forums table, therefore screwing up everything, etc. In short : it doesn't work. But, since noone in their right mind would use MyISAM for critical data, I include this result anyway, as a curiosity.

I had to write a repair SQL script to fix the corruption in order to see how MySQL will fare when it gets bigger than RAM...
