Yes.  The SHAPE field is indexed. I looked at the FILTER statement but not sure how I can implement that. All the examples I've seen for FILTER have static values.

Did you create spatial indexes on your MySQL tables?

> I have data stored in MySQL. When I configure the map file to pull from a small subset of the data, tiles are generated correctly. If I change the map file to point to the larger master table, map server returns "CGI Timeout". I dont't really want to breakdown the master data table into hundreds of smaller tables. I need additional informaiton and/or suggestions on how to get mapserver to work with millions of rows of data in MySQL.
