So it turns out the slowdown had nothing to do with file access (which I did optimize a little but had little impact). It was due to major inefficiencies with the third party control I was using to display the entries. I switched to a ListView based implementation provided by Microsoft, and now it's much faster. Hopefully this will help users even without changing the storage location.

As a side note, you should have been able to move the storage location from inside the app without having to go through all those steps...
