do not compare results from OS4 Blender 2.48 with MorphOS Blender 2.46. Use native MorphOS Blender version instead if you really want. I still strongly suggest you to download DigiRoller for MorphOS, then the benchmark DBM file, load the DBM module to DigiRoller and perform SpeedTest. It really doesn't take more time than modelling in Blender.
