怎么让CT的CPU利用最大化？或者是怎么确定他目前是不是最...

大家，想榨干CT的最后一滴资源，

CT安装fedora后，他的CPU利用是不是最大化的呢。

可能这个问题有点蠢。希望高人指 点下。

Setting CPU Frequency

Cubieboard CPU frequency can be adjusted in real time, , the following file save as shell file, or placed in / etc / rc.local before the exit 0 can be executed. Specific CPU frequency maximum and minimum values ​​can be set based on usage .

  #!/bin/sh
  echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
  echo 1000000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
  echo 600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
  echo 25 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
  echo 10 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor

After testing, Cubieboard single core version (A10) CPU frequency can be overclocked to 1.2GHz, stable operation (would be better to stick a CPU heatsink); Cubieboard dual-core version (A20) can also be overclocked to 1.2GHz

提高cpu频率
还有sys_config可以提高ddr频率


使用top指令可以看到系统的资源消耗

HI 多谢啦！    看到这个是cpu0 ， 是不是代表两个CPU都一样
