Sleep for 1s before checking the newly updated value from "/sys/devices/system/cpu/cpu%u/cpufreq/cpuinfo_cur_freq", because for some systems it may not be effective immediately. 2. The value in "/sys/.../cpuinfo_cur_freq" may not be exactly the same as what we set. For example, we write "2400000" to "/sys/.../cpufreq/scaling_setspeed" to set the frequency, then the value in "/sys/.../cpuinfo_cur_freq" may be "2401222". So need to round the value.
