Most triple-pattern-match queries (even reasonably complicated ones) come in at a few 10s to a few 100s of milliseconds. Label search queries are slow because they rely on a regex table scan - I'd be interested in strategies to speed this up (maybe a python lucene equivalent[1]). I use veudas for interactive knowledge management servicing a handful of people, so anything under half a second is fine for me. Sorry about that - I feel a bit silly saying 'fast' now. I'd be keen to benchmark it if anybody has some example data + queries to try. Cheers, Phil [1] http://www.divmod.org/Home/Projects/Lupy/
