Kicking a Sun out the door if you can make a better linux box isn't 
linux elitist?

(/me wonders if you can get what you like better on sparc linux or
intel linux.)

If your problems are partitionable, not only do I agree to this point,
but I'll add, if you can find a part that's a bottleneck, and you are
saving *enough* extra money, maybe you can get an SDRAM hard disk for
the offender, and improve that aspect of response time amazingly.

(SSD disks were a topic of a BayLISA topic a few months ago.  BayLISA
members can borrow the tape if you want to check into it in more detail.)

On this I have to bow to the wit, flamage and general experience of those
who prefer to hang out with databases.

Other dependencies include whether the only Clued DB Dudes (of any gender)
you have are (1) able to pick up new flavors quickly, (2) prima donnae about
their DB preference.  And maybe, whether there's any politics about the SQL
flavor from the non-clued, but, if you solve enough $peed problems you're
likely to beat past that.

            this law?  It is simply that the program should always respond to 
            the user in the way that astonishes him least. -- Geoffrey James
