Hi! If you want you can re-compress GeoTIFF into ECW (directly supported by MapServer) using gdal_translate to save space. Even without break down to smaller tiles the performance is also very good, at least for my case (1.5Gb single file, 135093x67205 pixels).

""" Yes, you can... But remember, MrSIDs are COMPRESSED. I have a MrSID of my county that is almost 1GB. I wanted to serve it with MapServer, so I came up with "the plan"... 1) Break the MrSID into sixteen GeoTIFFs with mrsiddecode. 2) Create an index with gdaltindex. 3) Add the index to a mapfile. I created a small Python script to complete step 1... And wound up with sixteen GeoTIFFs that totaled nearly 15GB. ---- Nemo -- Iron County Forestry and Parks Dept
