The impacts I'd watch out for are;
- Payload size exceeded on the event bus. You should monitor the size and consider using "snapshot with selected fields"
- UI usability. (i.e. Profile layout "crowding", number of search facets, creating/updating entities, etc.).
- Impacts to DG processes (evaluating Potential Matches)
- Complexity or quantity of required match rules
Number of defined attributes isn't an issue per se, you need to determine % of populated attributes. If the entities are sparsely populated Reltio does a good job of mitigating the impacts. Also the type of attributes makes a difference (Simple, nested, reference). You should review Configuration Best Practices at a minimum you'll know what will be flagged during an engineering review.
