Hi,
I'm pretty sure that the performance of in() seems to have downgraded
somewhat with the new 6.1.0.3126 release of virtuoso; I'm struggling to
run even very simple queries such as the following without them timing
out, on both my own 6.1 and dbpedia.org's instance:
SELECT * WHERE {
?s ?p ?o . FILTER( ?s in(<http://dbpedia.org/resource/RDFa>,
<http://dbpedia.org/resource/Semantic_Web> ) )
}
Pretty sure this is a new issue as I can run similar queries (all be it
on a smaller dataset) on 6.0.1-pre1.3124 without any problems, and
likewise I've tested on the bio2rdf.org sparql endpoint and performance
is nice and fast as expected.
Regardless even if the above versioning detail is incorrect, the in()
performance definitely appears to be an issue on 6.1.1.0.3126
Many Regards,
Nathan
