You're welcome. Just to clarify, PostgreSQL isn't really a Pervasive product; we just have a bundled installer and offer support and services, but it's all the same as the community code. When it comes to tuning, http://www.powerpostgresql.com/PerfList and http://www.revsys.com/writings/postgresql-performance.html are a couple places to start looking. Finally, and luckily this applies to SQLite as well so this doesn't get too off topic :), PLEASE seek help/advice BEFORE spending a bunch of money on a big server! All too often I see people who spend a load of $$ on equipment they didn't need or won't be able to utilize because they didn't do enough research before hand. Granted, I'm biased since I make money on consulting, but the amount of money I've seen people spend on needless hardware would often buy a pretty good chunk of my time. -- Jim C.
