I noticed that LayerFactory.CreateLayer takes huge amount of time to add content of lyr file to a map. On my computer it takes more than 5 minutes to add simple layer (lyr file is attached – TestLayer.lyr).
I created simple test add-in to illustrate the problem (VS solution is attached – TestSlowCreateLayer.zip). Add-in contains the button (named Test slow CreateLayer) which calls

where layerFilePath is the path of attached lyr file (TestLayer.lyr). After method is executed the message box with execution time will be shown.
I can reproduce this behavior for every lyr file I take. Layer data is very simple as you can see.
Also I noticed high CPU usage for ArcGIS Pro while layer is being created: 70-80%.
Environment:
CPU Intel Core i5-7200U
8 GB RAM
ArcGIS Pro 2.1
My add-in should work in ArcgIS Pro 2.1 so I need to get it work good on this version. I suppose 5 minutes for provided lyr file is more than it should be.
