[gdal-dev] Gdalwarp speed comparison

I made some time ago a few measurements about the speed in of reprojecting
images with gdalwarp and and another software.  Results can be found from here:

Another software had an option to use an option called "Speed optimization"
which had a big effect on speed. It believe it relates somehow to warping either
in bigger blocks or pixel-by-pixel. I wonder if gdalwarp is utilising something
similar because it tends to be so fast?
