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: optionsSMP# Symmetric MultiProcessor Kernel optionsAPIC_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.
