[mapserver-users] Ed's Rules for the Best Raster Performance

[Brent Fraser]

In honor of Ed's imminent retirement from the Mapserver Support Group, I've put together "Ed's List for the Best Raster Performance":


#1. Pyramid the data 
        - use MAXSCALE and MINSCALE in the LAYER object.

#2. Tile the data (and merge your upper levels of the pyramid for fewer files).
        - see the TILEINDEX object

#3. Don't compress your data
        - avoid jpg, ecw, and mrsid formats.

#4. Don't re-project your data on-the-fly.

#5. Get the fastest disks you can afford.
