So this actually just happens now in production...
https://www.wikidata.org/wiki/Special:EntityData/Q148.nt

Other formats like ttl and json etc seem to work, only nt seems to fail?
is nt the only one that does this crazy resolveMentionedEntities?

Pinging @Ladsgroup as he recently touched something in T255305 that may have affect load times.

I mean adding a better revision id lookup (using the cached service in core) would definitely improve things but one thing in general: Rdf output if is not on dump flavor, loads all entities that are linked in it (all items, properties, etc.). I filed T243950: RDF output of an entity loads all referenced entities, it shouldn't in Jan for it.

I'm aware this task is older than T281272
However T281272 has more details and is already picked up on a team workboard, so I am opting to merge this task into that ticket.
