How to increase the speed of spatial query

hi all, I am using ArcGIS API for JavaScript v4.3 queryFeatures to get features in a layer.

 

var query = new Query({ returnGeometry: true, outFields: ["*"] });
query.geometry = geometryEngine.union(geometries);
self.censusLayers[layerID].queryFeatures(query).then(function (results) {
   //task/
});

 

Is there a way to increase the speed of execute this query? (assume the query geometries will be a 30 km radius circle and the query result will be 8000 SA1 geometries)

 

Thanks.
