The beauty of the Sail Ouplementation model is that it is optimized for both index-based queries (spgo) and traversal-based queries. If you look at the technologies in OpenRDF, they are very "index-based" (SPARQL, getStatements(), etc.). While, with Blueprints GraphSail, you can use this API (implements Sail), you can also "drop down" into native Blueprints or Neo4j and thus, have a quad-RDF graph represented as a linked list structure and thus, do fast traversals. It is a bit of the best of both worlds in that sense... In terms of performance benchmarks, we don't have any right now as GraphSail is a recent addition to Blueprints and is still being heavily developed/optimized. Also, I believe AllegroGraph has a disk/memory representation these days that makes for fast traversals (used in their SNA package) so you might want to check them out. Also, see StarDog which is a full Java-based RDF quadstore ( http://stardog.com/ ) which has Gremlin as their distributed path-based language. Finally, most RDF stores provide full text search. Moreover, Neo4j does as well.
