Given the reload speed, approach to more continuous updating
<https://github.com/ad-freiburg/qlever/wiki/QLever-support-for-SPARQL-1.1-Update>,
and recent performance
<https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/WDQS_backend_update/WDQS_backend_alternatives#A_Report_on_Using_QLever>
 benchmarks
<https://github.com/ad-freiburg/qlever/wiki/QLever-performance-evaluation-and-comparison-to-other-SPARQL-engines>
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
