Would you please point out some cases when HTT with machdep.hlt_logical_cpus=0 causes worse performance than machdep.hlt_logical_cpus=1? I am using an HTT Xeon since recently and in my tests it showed that machdep.hlt_logical_cpus=0 is better! A simple ubench (spawning 2 processes) gives better results in 0 mode! Thank you in advance!
