\* 750 / 1000)

echo 95 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold

echo $SAMPLING_RATE > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate

自己主动更改governor 与 I/O 调度

a) I/O 调度 (最佳: MTD 设备 – VR; EMMC 设备 – SIO) – 须要适应的内核

參数:

echo “vr” > /sys/block/mmcblk0/queue/scheduler

or

echo “sio” > /sys/block/mmcblk0/queue/scheduler

b) Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) – 须要内核支持.

echo “governor-name-here” > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

12. 启动时自己主动-zipalign apk

(须要zipalign二进制, 位于 system/bin/zipalign, 可參考下面网址自行加入)
