There is now a performance problem class, that is caused by a large network of databases, that are interlinked with each other.

The effect often is, that one element changes, and this causes a lot of changes in other tables. This can be created with a number of APIs:

• [ ] Using lookups with predicates, that are dynamically created.
• [ ] Implementing ratings in such a way, that every line rating in a group is updated, even though just 1 really changed.

It would be nice to have an option, that enables code, that helps to find performance problems:

• [ ] Create statistics for databases, columns and lookups in general.
• [ ] Create statistics for constraint calculations. Determining the number of rating events per new allocation or deallocation, on average, would probably help in a lot of cases.
• [ ] Render results on web server.
