true - but surely this is a bug in FreeBSD ? man smp says: "Since using logical CPUs can cause performance penalties under certain loads, the logical CPUs can be disabled by setting the machdep.hlt_logical_cpus sysctl to one." I have: websvr04# sysctl machdep.hlt_logical_cpus machdep.hlt_logical_cpus: 1 but I am still seeing 4 CPU's as I have two physical processors, each with two logical ones onboard. I find it very hard to believe theres a bug in something this basic though, as it's specificly mentioned in the relase notes as being there to disable hyperthreading... very odd... -pete. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
