Performance of scholarly test server?I was hoping to do performance comparisons at some point but I don't think that's going to be possible - I was looking for a certain sample of article items and ran this query:

PREFIX wikibase: <http://wikiba.se/ontology#>
PREFIX ps: <http://www.wikidata.org/prop/statement/>
PREFIX pq: <http://www.wikidata.org/prop/qualifier/>

select ?item ?stated_as WHERE {
?item p:P50 [ps:P50 ?author; pq:P1932 ?stated_as] .
FILTER(wikibase:isSomeValue(?author))
} LIMIT 10
