Tiled TIFFs
See also GeoServer.
Convert TIFF (tif+tfw) to GeoTIFF with GDAL:
gdal_translate -of GTiff -co "TILED=YES" input.tif tiledGeotif.tif
By using the TILED=YES parameter we ask the command to prepare the file for tiles rendering. Now the size of the resulting file is larger.
Then create overviews for the GeoTIFF file:
gdaladdo -r average tiledGeotif.tif 2 4 8 16
