Does the CPU frequency scaling affect the performance of vcv rack?


(David Rodriguez) #1

I just realize myCPU frequency scaling governor is set to “Power Save” mode , can it affect the performance of vcv rack?

actually I have a very nice performance, but I wonder, if i change the settings to “performance” how it affect to VCV rack?

Yes, CPU power saving modes either decrease the CPU frequency or force it to sleep every X microseconds. This has a proportional effect on Rack’s performance.

awesome, nice to know that…

I think that is something that all we the ubuntu users need to know, ubuntu is setting by default as power save mode.

to change this, in Terminal, enter the following line of code:

echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

Press enter

Your power settings will now be set to “High Performance” mode

to set it back to power save mode

echo powersave | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

enter
