I'm pretty sure that it uses Altivec by default on PPC. (The only hand coded Altivec code is in the gr_fir_fff filter.) Do your results look like this: http://gnuradio.org/images/perf-data-images/ps3-altivec.png or like this: http://gnuradio.org/images/perf-data-images/ps3.png The PPC on the Cell is seriously lame, as you have no doubt found out by now...
