Re: One particular large database application

AFAIK google uses thousands of pcs with IDE drives. So going the multiple
PC way can work.

Not sure how that would be implemented for postgresql. It seems simple to
support _many_ read only queries at a time using many pcs. But how would
one speed up a few large parallel queries that way?

Cheerio,
Link.
