Well honestly that isn't true either. Linux is faster then Solaris for PostgreSQL in a lot of cases. In reality... I would say the best OS for PostgreSQL is either Linux or FreeBSD. Win32 is great for a small installation or development. The Solaris argument may change for 8.2, I don't know. > Many tools aren't quite there on the windows version, and it > still seems to have more issues with performance and scaling than the > unix flavors of PostgreSQL. No question. The win32 version of PostgreSQL can't go over 300-400 connections depending on the size of your machine without modifying your registry in a scary fashion. > >> As for hardware, until recently, AMD was the un-disputed king when it >> came to running PostgreSQL (and databases in general).

I am still curious about this when you start talking more then say 4 CPUs.

I am particularly fond of LSI but Areca has PCI-Express cards which means you can put them on cheaper motherboards :) Joshua D.
