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.

Hi,
The "wikibase:label" service is know to consume and it timeouts often (nothing new it happens since the beginning ; but as Wikidata grows, it's more or more visible).
This simplified version of the query works (without intermediate variables and without the service): https://w.wiki/9yR
Cheers, ~nicolas

I noticed few timeouts on example queries, for example
Is it correct to have this condition ?
