What version are you using ?

Could you be a little more specific on your performance issues ?

The usual way to deal wih them is tuning your db structure and/or
queries or 
setting backend options to use more memory for stuff or other such
things. 

If there is something wrong with the structure or queries, then a
database 
switch will help you very little, unless your front-end tool has some
special
support for _some_ databases and not for others.

The usual - Oracle, Interbase, Informix, DB2, Sybase, Solid  

The website is usually obtained by putting www inf front and com at the
end ;)

And let us know of your results.

Is FreeBSD a religious issue there or can it be negotiated ?
