something like this would be useful for advanced tuneing, but the biggest 
problem is that it's so difficult to fingoure out a starting point. bad 
choices at the starting point can cause several orders of magnatude 
difference in the database performsnce. In addition we know that the 
current defaults are bad for just about everyone (we just can't decide 
what better defaults would be)

this horrible starting point gives people a bad first impression that a 
simple tool like what's being discussed can go a long way towards solving.
