Your 2GHz P4 is a later stepping which has HTT also, ours is: CPU0: Intel(R) Pentium(R) 4 CPU 2.00GHz stepping 04 Total of 1 processors activated (4003.47 BogoMIPS). as Debian dmesg tells it. But I still don't know whether it's nowadays safe and/or advantageous running hyperthreading on these CPUs in FreeBSD? Anyone? cheers, Ian
