Performance issues in KanbanBoard

The performance of the KanbanBoard is poor when there are several hundred cards. 

Especially when the following operations are performed:

  1. Manually updating 'ColumnMappingPath' property of card
  2. Manually updating 'SwimlaneKey' propety of card

Steps to reproduce:
  1. Define KanbanBoard with ~50 columns and bind to "Columns" property
  2. Define ~10 cards for each column and bind to "ItemsSource" property
  3. Create a timer, that fires every 5-10 seconds and do the following:
    Take around 20 cards and update manually the "ColumnMappingPath" field to a new column and also update the "SwimlaneKey" field to a new group
