https://community.esri.com/t5/arcgis-online-questions/performance-reduced-in-mapviewer-with-search/m-p/1715786#M69348 <P>Hi, I believe the 'Search Layers' input form is causing performance issues with MapViewer. This allows you to filter the list of layers which is handy but might also be problematic.&nbsp; Prior to this appearing there was a similar feature available on the Map Layers widget on Experience builder.&nbsp; This resulted in extremely slow performance when a lot of layers were present. Maybe due to it scanning the list continuously?&nbsp; In experience builder once we had identified the issue we could just turn it off and good performance resumed.&nbsp; Now this is added to MapViewer we are seeing worse performance again in the MapViewer, but quicker performance on the Experience Builder app.&nbsp; This suggest that may be the problem?&nbsp; Could this be either improved to avoid Performance issues, or a setting to turn it off?</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Search Layers input form" style="width: 374px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/155735i8D55BEEBE4C44448/image-size/large?v=v2&amp;px=999" role="button" title="Screenshot 2026-07-22 102435.png" alt="Search Layers input form" /><span class="lia-inline-image-caption" onclick="event.preventDefault();">Search Layers input form</span></span></P> Wed, 22 Jul 2026 09:32:37 GMT JoeNunn 2026-07-22T09:32:37Z https://community.esri.com/t5/arcgis-online-questions/performance-reduced-in-mapviewer-with-search/m-p/1715786#M69348 <P>Hi, I believe the 'Search Layers' input form is causing performance issues with MapViewer.
