> The "wikibase:label" service is know to consume and it timeouts often
imho: We can use subquery for optimization so the label service doesn’t have to do as much work https://w.wiki/9zD ( LIMIT 1000 + Labels + Descriptions ) LIMIT 10000 - 6924 results in 59861 ms ( birthday = 13 October 2014 ) LIMIT 1000 - 1000 results in 12050 ms the ideal case will be - if the sparql engine can detect and automatically optimize this type of queries.
