If my memory serves me well, the Open Source version of Virtuoso
doesn't have certain scalability features that would be necessary to
run a graph as large and dynamic as Wikidata's. Is this information
out-of-date?
Cheers,

Yes, that information is out-of-date. Uniprot is a 180 Billion+ instance
of Virtuoso Open Source Edition running on commodity hardware.

Given the reload speed, approach to more continuous updating

and recent performance

benchmarks

from
the page you referenced, QLever seems pretty magical. [it was
less so when the initial evaluation of backend alternatives came
out] It's also cheap enough to run at home that some people are
scratching their own itch now when they have queries that time
out on WDQS, as Peter highlights.
Iterating on that benchmark until no one has any concerns with
its applicability to our use case seems like a short-term
high-return investment. SJ
Is there a place where SPARQL URLs for the various benchmarks are
collated? SPARQL makes transparency dead easy via SPARQL URLs.
I am also very interested in what "numerous hurdles" is supposed
to imply regarding Virtuoso when its installation boils downs to;
1. Run an installer (you don't even need to build its Open Source
Edition binary).
2. Start server
3. Start interacting with SPARQL via the instance endpoint.
