How far have you pushed PT & which hardware?

Hi all,

I'm going to be doing quite a big niche affiliate site in 2007 and was wondering how your hardware's coped with price tapestry.

I've had price tapestry running on a shared server with 300 accounts, and it easily searches 10,000+ products from three merchants very quickly. I'll have a lot more on my next project, so I'm interested in knowing what sort of hardware I'll need.

What's the most merchants/products have you had searchable? How long did searches take? Which hardware?

Cheers :)
