Hi Kuro, I don't know of any benchmarks featuring distance-sort performance.
Presumably you are using SOLR-2155 because you have multi-valued spatial fields? If so, LatLonType is not an option. SOLR-2155 sorting performance is *probably* about the same as the equivalent in Solr 4 RPT. If you actually do have single valued spatial to sort on, then definitely don't use SOLR-2155 or RPT for that, use LatLonType. It's surely faster but I haven't measured it. The best multi-valued distance sort option for Solr 4 is currently this: https://issues.apache.org/jira/browse/SOLR-5170 ~ David On 11/5/13 1:36 PM, "T.
