Yes, you did.
I wrote "/sys/devices/system/cpu/cpufreq/ondemand/up_threshold" and
you tried "/sys/devices/system/cpu/cpufreq/performance/up_threshold"
There is no up_threshold in the performance governor, as it is always maxed out.
There is that parameter for the ondemand governor (where CPU speed varies according to the load).
I provided two alternatives:
- use the performance governor (which you have now figured out),
echo performance > /sys/devices/system/cpu/cpufreq/policy0/scaling_governor
or - tweak the parameters for the ondemand governor to modify its behaviour to be more eager to max out the CPU.
echo 35 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
...
ondemand has several parameters that were also mentioned/discussed in those threads.
