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
