Andy Seaborne commented on JENA-1300:
-------------------------------------
(which version?)
You may find that reversing the order to put the {{rdfs:label}} first helps or
using {{UNION}} not {{|}}.
This is all highly dependent of the size and shape of the data. If run as the
first query after restart, then TDB is stil warming up as well. Machine
hardware is a factor.
> Using alternative path in Fuseki runs forever

> Project: Apache Jena
> Issue Type: Bug
> Components: Fuseki, TDB
> Reporter: Natan Cox
>
> When doing a query with alternative paths like in this example 'isOwnedBy'
> and 'exploitatie' then Fuseki seems to run forever.
> If I remove on of the 2 the response is immediate.
