It says in the brochure that it has "HyperThreading", which I think is somehow related to the HyperThread thing in the FreeBSD kernel, right? I know there's this message in /usr/src/UPDATING, which unfortunately does not clear up the matter for me. So let me recap what I believe to understand: For utilizing the advantages of this HyperThreading stuff for users, I need in the kernel configuration: options SMP # Symmetric MultiProcessor Kernel options APIC_IO # Symmetric (APIC) I/O Furthermore, I need to set "machdep.hlt_logical_cpus" to 0 (zero). How do I add this to "the loader" so that it is set to zero at every boot up? Should I simply add to my /boot/loader.conf a line like: machdep.hlt_logical_cpus="0" After that, I'm done with the hyperthreading? Thanks, Rob. PS: if you're in the mood, I would appreciate a few words on what this HyperThreading is about and what advantages I can expect. Thanks too! _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]" _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]" _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
