If adding a LIMIT makes the query work, we can just edit the example to
have the said limit. It is only an example query, it doesn't have to
return all the results.
Cheers,

Thanks all for the explanations, now my point is
on the examples as seen
by some first Wikidata users: if the examples are there and fail, that's
disappointing.
Have we to comment out examples that could fail ?
Should we mark this ?
I don't like the latter, but if it is a
contingent situation it makes sense.
Till the work load is not
managed, e.g. by optimizations, can we increase the
timeout ?

Thanks

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):

Whose birthday is today ? [1]
Is it correct to have this condition
