Dear Ivan,
Thank you for the very detailed answer!
We will investigate whether solution #3 would work for us. 500x
performance improvement sure would be nice:-)
Kind regards

Hello Oliver,
The cost of "variable P" heavily depends on the sample query.
1. In good case the overhead is zero. It's possible when graphs (G) are
known or almost all data of the dataset are in very numerous small
graphs, so it's cheaper to read whole graphs than to try to use
additional indices
Dear Virtuosans,
I noticed that queries can be much slower when using variables as
properties (even if the variable can only have one value) e.g.:
DATA (extract):
:display :startRelation :posStart.
:gene0 rdf:type :Gene.
:gene0 :posStart "53416"^^xsd:numeric.
:gene1 rdf:type :Gene.
:gene1 :posS
