I have queried small triplestores with SPARQL and experienced near
instantaneous responses. 20,000 should be trivial for in-memory queries.
I suspect you're doing something slow in your query, rather than there
being something odd in your data model.
Would you like to post the query?

I have Redland model with 20,000 triples using the Berkeley DB
storage option. I am performing a sparql query using
librdf_new_query() and librdf_query_execute() to search for all
people that are male and born between two dates.
There are a total of 500 people in the model. Each person has a sex
property and a birthday property (among others). It took over 8
minutes for librdf_query_execute() to complete on a dual core 2.16
GHZ processor with 2 gigabytes of memory.
Is this the expected behavior?
Thanks in advance
