Hello Fabrizio,
It seems that the problem comes from SERVICE wikibase:label. As said in another discussion, the query executes in less than one second if you rewrite it in this way https://query.wikidata.org/#SELECT%20%3Fistanza_di%20%3Finstanza_diLabel%20WHERE%20%7B%0A%20%20%3Fistanza_di%20wdt%3AP31%20wd%3AQ13442814.%0A%20%20%3Fistanza_di%20rdfs%3Alabel%20%3Finstanza_diLabel.%0A%20%20FILTER%28%28LANG%28%3Finstanza_diLabel%29%29%20%3D%20%22en%22%29%0A%7D%0ALIMIT%2010 .
Cheers,
Ettore Rizza

Hello all, the following query ends with a timeot:
SELECT ?istanza_di ?istanza_diLabel WHERE { SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". } ?istanza_di wdt:P31 wd:Q13442814. } LIMIT 10
Can anybody explain why ? Thanks in advance
