在两台rockchip rk3288上面测试benchmark，均达不到项目文档上面的速度，这是什么原因导致的

1. rockchip rk3288上面实测benchmark速度

项目上面rockchip rk3288速度

adb root adb shell stop

echo "performance" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor echo "performance" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor echo "performance" > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor echo "performance" > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor

注意输入电压要足够

电源是POE供电，调整了主频，速度有了较大上升，不过还是达不到文档上面速度，另外最高频实测sdk resnet18-in8模型速度要486ms，离benchmark速度差距较大，有什么办法可以缩小这差距吗

top 看下是否有其他进程也在使用cpu资源 你的表格里4线程比2线程慢是不正常的
