Any guesses would be wild ones, but I'm pretty sure you'll notice it, assuming the result size isn't trivially small. Also, LatLonType will use much less memory and be more real-time search friendly (i.e. Commit warming will be faster, assuming you do warming queries as everyone should do).
To be clear, I think you should continue to use SOLR-2155/RPT for spatial filtering -- that's what that technology does best. ~ David On 11/6/13 3:22 PM, "T.
