I have isntalled a Portal server 10.5.1 and web adaptor (IIS) 10.5.1 in single machine environment. The web adaptor is configured to access the Portal. I have also implemented IWA on Portal.
The porblem is that the performance of Portal is slow after setting up IWA. It takes nearly 2 minutes to open a map application, which has only a basemap layer, a point layer and few buttons e.g. measure distance, filtering. Anyone have ideas? Thanks.
