Do you know if this also works if you replace i386 packages with recompiled i686 ones? If so has anyone actually benchmarked a system with a standard install vs the same packages recomiled to i686. The reason I ask is that my requirement for linux is for intensive number crunching and so to get a 5% to 10% performance increase would be sufficient justification for recompiling - on the other hand no good if you can't kickstart from it. cheers -- Geoff Dolman JDRF/WT Diabetes and Inflammation Laboratory Cambridge Institute for Medical Research University of Cambridge http://www-gene.cimr.cam.ac.uk/todd/
