a value in a PostGIS data type is usually larger than standard data. Is it possible that the bandwidth between you and RDS is just smaller than the bandwidth versus your (presumably local) Windows box and the extra time is lost transferring data?<br></blockquote><div><br></div><div>How do the two systems compare (operating system, processors, cpu speed, memory)?
