After Athlon patch:
clear_page() tests clear_page function 'warm up run' took 17860 cycles per page clear_page function '2.4 non MMX' took 11805 cycles per page clear_page function '2.4 MMX fallback' took 11777 cycles per page clear_page function '2.4 MMX version' took 12003 cycles per page clear_page function 'faster_clear_page' took 4416 cycles per page clear_page function 'even_faster_clear' took 4315 cycles per page
copy_page() tests copy_page function 'warm up run' took 14930 cycles per page copy_page function '2.4 non MMX' took 23337 cycles per page copy_page function '2.4 MMX fallback' took 23314 cycles per page copy_page function '2.4 MMX version' took 20293 cycles per page copy_page function 'faster_copy' took 9159 cycles per page copy_page function 'even_faster' took 9071 cycles per page
This is with 2.4.9-ac12-preempt1 in both cases and niced to -20. Subsequent runs are very similar.
