In a similar machine (core 2 duo with squeeze) with kernel 3.2.0-0.bpo.1-686-pae it uses ~12% cpu, which is 24% of one of the processors. My machine is an i5 running sid in amd64 and it uses ~1.5% cpu which is 6% of one of the processors. Just for fun, I also tested ogg123 in a atom single core machine running squeeze, kernel 2.6.32-5-686, eating 2% of the cpu. :) The vorbis-tools package is the same in the four machines, so I think the problem is not in the vorbis-tools package. Seeing this results I think the problem might be a issue with threads migrating between cpus, which shouldn't happend. It would be great if you could test it with the kernel 3.2.0 from backports.debian.org. Thanks, -- "If you optimize everything, you will always be unhappy." -- Donald Knuth Saludos /\/\ /\ >< `/
