View methods overloading low performance

[Nice3point]

Execution of some methods takes quite a long time, about 4 seconds which is critical

Method	Screen
CanCategoryBeHidden (ElementId)
IsCategoryOverridable (ElementId)

The reason for this is the presence of DWG links inside the families:

Should these methods be disabled or are they informative and should be kept?
In models without DWG they are executed 16 ms

Maybe this methods that require category as input should be generated only if the user click in the method, if the project have a lot of categories RevitLookup is checking for each one even if the user does not need that information.

I wonder how many categories do you have in this 4 second sample.
