Semantic Search - Faceted Search and Web 3.0 for Drupal

The (Slowly) Open Sesame article here provides an honest assessment of using Sesame for real world applications.

Here's an excerpt:

Until recently, Sesame 1.x has handled this rather well. I had to do some work on the auto-generated queries, some pre-optimization, to squeeze a little better performance out of them, but for the most part, the query response time has been adequate for development and testing. But we’re now we’re trying to test jSpace against non-trivial sized data sets, including my favorite, our scrape of the Retrosheet.org baseball data, which is about 7.5M triples.
