There is one difference for CPUs, so I sometimes run scripts like this: echo powersave | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor >/dev/null 2>&1 echo ondemand | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor >/dev/null 2>&1 "powersafe" for Intel and "ondemand" for AMD, >/dev/null 2>&1 to redirect error messages. "performance" is equal for Intel and AMD and by default this should work! VitualBox emulates a CPU, by using the real CPU. The guest is not able to change settings of host and I could imagine there's no simulated CPU frequency scaling available.

Homer, testing Floyd, said, "Five times nine", and Floyd instantly responded "Forty-five", which impressed Homer. -- ubuntu-studio-devel mailing list ubuntu-studio-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-devel
