spatial search performance - latlontype vs pointtype?

I've switched my index to use pointtype instead of latlontype of spatial search queries. Unfortunately I'm seeing much worse performance, and I was wondering if anybody else knew of any issues between the two types. I would expect a flat space calculation of pointtype to be better than the spherical calculation of latlontype… is this an incorrect assumption?

I saw a message from last July on this subject that hinted at latlontype being preferred, but that was as far as it went: http://mail-archives.apache.org/mod_mbox/lucene-solr-user/201107.mbox/%3CCAH0thKB6LG5PU-R-iULGf77tnZBjLpXiSostB_NZQz-UbLubDA@mail.gmail.com%3E

Thanks,
Nick
