RE: Tools for 20 million triples?

Charles, 

Have you seen:

http://sourceforge.net/projects/threestore

It has been developed over the last few years and easily supports
several million triples. (Some performance info
http://inanna.ecs.soton.ac.uk/3store/performance.php) Not sure how well
it scales to 20 million, but it has been developed with performance in
mind. It also offers an RDQL and OKBC interface.

Example of where it has been used:

Good Luck!
