Re: [PD] how to optimize system for pd performance?

Hallo, Roman Haefeli hat gesagt: // Roman Haefeli wrote:

i encountered, that 'ondemand' cpu scaling doesn't work correctly when running pd with realtime priority. even if pd is using 80% or more resources (of one core), the cpu frequency is not raised and staying at 800MHz. i can force it to go up by running an instance of 'burnMMX' (or something else, that burns as many cycles as possible). when running pd with '-nrt', automatic scaling works fine. also, as a workaround, i can set the scaling_governor to 'userspace' and then set the cpu frequency manually.

I don't remember being hit by this, but my memory may trick me. I'd use cpufreq-set(1) as root to switch the scaling governor to "performance" when performing.
