1. Scalability -- Our triplestore would be HUGE. I'd estimate 10-20 Million triples. Is that small or large in RDF circles?

That's fairly large. Leigh Dodds will have something to say on this
topic, having used very large sets of triples.

Our store is pretty big -- its about 200M triples.

We're currently using Jena on Postgres. For our needs this worked out better than Jena/MySQL, Sesame, and Kowari.

(SPARQL/RDQL) Query performance times are pretty patchy and poor across the board. Direct resource lookups are generally very fast though.

From our testing we found that a store backed with a relational database proved to be the most stable and easiest to manage.

Cheers,
