I have worked with higher volumes then mentioned, in past. it works well unless:
1. The tenant is not licensed for such high volumes
2. The data model is not designed efficiently causing too many duplicate for an entity e.g., surrogate key can be used if a location/site has too many contributors
3. Match rules are not tunned appropriately which will result in too many potential matches false positives
