Geometry calculations and multiple feature lookups tend to run smoother server-side, especially when layers are large. Client-side logic still works well for lightweight, UI-driven expressions. Clear guidelines would definitely help when deciding where each expression should be executed.</P> Sun, 30 Nov 2025 16:04:53 GMT https://community.esri.com/t5/arcgis-dashboards-questions/arcade-performance-client-side-vs-server-side/m-p/1669261#M11668 SteveMarkovick 2025-11-30T16:04:53Z
