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

[Jeff McKenna]

my quick comments:

- adding overviews with GDAL's 'gdaladdo' utility is very important
- I find your use of the word "pyramid" confusing (this seems to be a 
word that Arc* users are familiar with but has no real meaning in the 
MapServer world...I guess I've been on the "good" side for too long ha)
