I noticed somebody suggested trying SMP with hyperthreading disabled in the BIOS, and I'm a little bit confused as to what sort of results should I expect from that. Could anybody enlighten me about how the OS will see/make use of this? My next test(s) will probably be: - "SMP w/ HTT" vs. "GENERIC w/ HTT disabled in BIOS" vs. "SMP w/ HTT disabled in BIOS" - both lmsensors and unixbench tests - timecounter comparisons But it may be a while before I get around to it as I'm busy with school. -- Kian Mohageri
