Zusätzliche Informationen
The issue happens on the server end. There are no plans on addressing it in ArcGIS API for JavaScript.Workaround
When performing a query with the goal of returning a count of features, a possible workaround is to place the following JSON in the in the outStatistics (Output Statistics) parameter at REST while returnCountOnly remains false: [{ "statisticType": "count", "onStatisticField": "ObjectID", "outStatisticFieldName": "OIDs"}]This method results in the query results being returned in under 1 second.The Javascript API should use the outStatistics parameter instead of returnCountOnly when retrieving a count of features in a layer upon adding the FeatureLayer to a map.Schritte zur Reproduzierung
