I don't see why that should matter. Sure, on a more complicated and slow query, retrieving an already calculated result will be faster. However, retrieving even the simplest of results from memory should be faster than opening a file on disk, preparing a db handle, querying, and then returning the result. At worst, it should be about the same, not 30% worse!
