I want to speed up it. And it looks I should change /boot/boot.script, but I didn’t find that file:
It's selecting a cpufreq to match operating system load...
cat /proc/cpuinfo is only a one time valid value for cpu speed, run
"cpufreq-info" and put the device under load..

Report errors and bugs to cpufreq@vger.kernel.org, please.
analyzing CPU 0:
driver: omap
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 300 us.
hardware limits: 275 MHz - 720 MHz
available frequency steps: 275 MHz, 500 MHz, 600 MHz, 720 MHz
available cpufreq governors: conservative, ondemand, powersave,
userspace, performance
current policy: frequency should be within 275 MHz and 720 MHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 720 MHz.
cpufreq stats: 275 MHz:5.44%, 500 MHz:0.35%, 600 MHz:0.31%, 720
MHz:93.90% (5669)
Regards,
Robert,
are you saying that the kernel dynamically changes the cpu freq
depending on the cpu load?
Oh, Thanks for that reply.
I also found if I use “cpufreq-set -g performance”, then cpu will be running at 720MHZ.
