One point I've in mind with my GDAL hat on is that GDAL has a number of x86 specific speed optimizations using SIMD intrinsincs in warping/reprojection resampling, overview/rasterio resampling, statistics computation, hillshading, gdalgrid. Currently we have no accelaration for other architectures. Even -- Spatialys - Geospatial professional services http://www.spatialys.com
