I have a listbox which has a datatemplate applied to the items. Each item id to display 3 text fields. The listbox is bound to an observablecollection. Everything is working fine, but when i try to load more than ~100 items into the collection, it starts chewing up all my CPU and takes ages to load.

Any suggestions?
