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.
