Speeding up load time for huge SHP files

[Nolte, Tim]

You'll really want to try break your shapefile up into smaller sections. I've got around 2GB of shapefile data I broke down into smaller shapefiles and this improved the loads time considerably. Once you get your shapefile broken down into smaller ones you'll want to be sure to run shptree on all the shapefiles, to index them individually. After that you can create a tile index of all the shape files. You simply reference the tile index shapefile as your data source in your map file. Check out the reference docs at the MapServer website for shptree & tile4ms.
