Re: Postgres vs Firebird?

while we're on "scalability", any thoughts on needs/plans for 64-bit PG?

With some of the changes Tom recently made in the code in CVS, PostgreSQL now looks capable of scaling to >4 CPUS
(somewherebetween 8 and 12 is where things start to drop off suddenly) while for firebird, handling >1 CPU is a
relativelyrecent development. 

I'd say try them both, benchmark them, and see what you think.  But keep in mind that you really need to use a 4+ CPU
machineto get a feel for the scalability of both in a large server environment.
