The most recent report http://statistics.netbeans.org/exceptions/exception.do?id=242262 shows 4s delay in 
DirectoryChooser. One idea that could improve the situation is to use FixedHeightLayoutCache. Possible?

I don't know, I never used FixedHeightLayoutCache. And I never saw such slowness even on very big folders (nb repo)
myself, so I assume this is low priority.
