Looks like 2 physical cores with 2 logical cpus which means each core has 1 logical CPU, which is true, because your cores lack HTT support. On a dual core chip with 2 HTT's per core it would probably be 2/4, yes? -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
