For the moment, until they fix an annoying bug in JAI so that i canj commit other tools, use the gdaladdo tool from the gdal utilities. You can download them from maptool.org. This utility is pretty straightforward. You should write something like gdaladdo -r average 2 4 8 16 32 64 -co "TILED=YES" sourcefile and it will embedde din the same tiff overviews with resolution decreasing bya power two at each level. 6 levels should be enough. The geotools plugin I wrote for tiff will automagically recognize the presence of the overviews and select the right one. Once you do this you will see REAL speed, believe me. > > > > >> I have a question.

The difference will be that instead of having a single image of 80 mb (which is not THAT big btw) you will have let's say 80 images of 1 mb and the result will be much faster. However if each image is only 80 mb using gdaladdo with the parameters I gave you above is more than enough. Try that out with the same parameters on each image, rerun the mosaicindexbuilder and then tell me if things are faster or not, if not you made a mistake somewhere :-).
