This issue happens on a Basic licensed ArcGIS Pro 2.2.1 (also in previous Pro versions) and when working with simple tasks like modifying feature classes (FC) records using the Attribute table that contain domains or subtypes. The bug also effects all geoprocessing tools in ArcGIS Pro. The effect of this bugs is that ArcGIS Pro is not usable and we had to stop using ArcGIS Pro because simple tasks take 400% longer than normal for ArcGIS Pro.
No change if Project is located on an SSD or network storage. The bug is consistent when moving to a new machines and/or users account.
The project file geodatabase consists of 24 fc and multiple subtypes and domains. But removing subtypes or domains dose not restore normal performance. Compact the FGDB does not resolve this problem.
Working workarounds (but not acceptable):
1) Instant fix when changing to Standard/Advanced Concurrent Use license in ArcGIS Pro 2.2.1
2) Delete number of records in FC to below 100
Issues addressed at ArcGIS Pro 2.2.0 that looks similar:
BUG-000111489: A feature class with hundreds of Domains and Subtypes has low performance with other tools.
ArcGIS Pro version: 2.2.1

Systems spec.: CPU and GPU way above ArcGIS Pro recommended specifications
