Do the following with your tiff image: gdal_translate -of GTiff -co TILED=YES gabungan.tif gabungan_tiled.tif And next: gdaladdo -r average gabungan_tiled.tif 2 4 8 16 32 64 Add gabungan_tiled.tif as a nee layer to your mapfile and compare it with the gabungan.tif layer. -Jukka Rahkonen- > Nonetheless, is MapServer more CPU-dependent or > memory-dependent?
