Quite possibly. jena-spatial is a lightweight solution using an external
index to using geo data - it is not GeoSPARQL.
(Just running a query once will incur a lot of start-up costs.)

Hi all,
I loaded geonames(40 million triples) into Fuseki and I indexed the data
into lucene.
The query below takes 4 seconds to execute. While a similar SQL one into
postgis takes 13 ms.
PREFIX spatial: <http://jena.apache.org/spatial#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT ?place
{
?place spatial:withinCircle (32.55668 -117.12865 1 "km" ) .
}
SQL
select geonameid from geoname where ST_Intersects(the_geom,
ST_Buffer(ST_SetSRID(ST_MakePoint(-117.12865, 32.55668 ),4326)::geography,
1000)::geometry)
Do I need to make any extra configuration on Fuseki to improve the
performance?
Best,
