SQLite SELECT very slow on Windows Phone

Simple SQLite SELECT query on Windows Phone is very slow on a high-end device (Lumia 930).

select * from tableName

It's fetching around 15000 records (yeah, I need them all) and normally I'd expect it to not be this slow. However, it takes around 12-13 seconds to get all the records. I'm using SQLite.Net-PCL client.

What could be causing it? Is it true that it's due to the very slow wrapper? Is there a workaround, any way to improve it?
