[Mapserver-users] Raster Image Limitation

[Gerry Creager N5JXS]

What are the particulars on the server?  Also, are you backing up to a 
database, or is this solely the rasters?  (Sorry, I'm looking at it now, 
but I've not had time to grok it all)... I'm thinking "Server" at this 
point, as you're moving a lot of bits and thus have a lot of diskIO.

If you're talking 'bout a SCSI-based RAID5, you've got some of the 
overhead covered.  If you're using a slow IDE disk, it's a lot worse.
