Hi all, I set "sysctl debug.cpufreq.lowest=800" but sysctl -a still told me that the CPU freq is at 300, though it will jump high if I am doing some heavy work. This reduce of performance makes me even have trouble on browsing website. Did I miss something important? 12:29pm kemian ~> sudo sysctl debug.cpufreq.lowest=800 debug.cpufreq.lowest: 0 -> 800 12:32pm kemian ~> sysctl -a | grep freq |grep cpu debug.cpufreq.verbose: 0 debug.cpufreq.lowest: 800 dev.cpu.0.freq: 300 dev.cpu.0.freq_levels: 1800/35000 1600/28347 1400/24803 1200/21260 1000/17716 800/8227 dev.cpufreq.0.%driver: cpufreq dev.cpufreq.0.%parent: cpu0 dev.cpufreq.1.%driver: cpufreq dev.cpufreq.1.%parent: cpu1 Best wishes, Kemian
