title: If class inherited many times can be slower?
body: <p>When i try to create good object hierarchy which will help to write less code and avoid to use unnecessary fields ,i feel myself free to create many base classes for good grouping which is usually abstract.
  What can be disadvantage of doing it like that ? Many times inherited class can be slower ? 
  To see many unnecessary abstract classes which hasn't enough good naming can cause confusing when encounter it in intelli-sense(auto-complete) ? What can be other else ?</p>
