Some info about RDF Gateway relevant to your problem...

We've got an online demo querying 250+ million triples and have a customer
achieving sub-second query response -- generating faceted results -- across
2+ billion triples.

Native store is not currently clusterable, but we recently added support for
SQL Server as a storage engine as part of some integration work we did for
Microsoft (for a problem space very similar to yours). So with that option,
we can leverage SQL Server's clustering support.

RDF Gateway has a built-in high-performance HTTP interface (as well as
OLEDB, JDBC).

Some somewhat out-of-date perf numbers (but still generally relevant):
