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.
