We are still working on improving SPARQL performance, but since SPARQL is by its very nature a very expressive query language not everything can be super-fast. > 4.

The KiWi SPARQL implementation since last version contains features for full-text search as part of SPARQL queries when using PostgreSQL: http://marmotta.apache.org/kiwi/sparql.html Greetings, Sebastian
