Hi,
Can we please consider adding a new function (Layer Optimization) in the next release of ArcGIS Enterprise Portal.
https://doc.arcgis.com/en/arcgis-online/manage-data/manage-hosted-feature-layers.htm#ESRI_SECTION1_7...
Currently this is only possible in layers hosted in ESRI AGOL. Having this function in Portal will greatly help optimizing things in feature layers.
