Performance Matrix Roon Server

Btw, do you know if there has been some changes to the code concerningthe processiong speed indicator?

I seem to recall reports of performance figures up in the thousand x’s?

Yes, the performance indicator was changed as the devs did not feel it was giving as useful information as it could. See:

Iqaudio DAC running Dietpi - shows up with icon like it's a RoonReady style device

At some point, we changed it so processing speed is only shown if it’s slower than 100x. It’s kind of silly to show Processing Speed: 2400x when just applying volume leveling, or when crossfade is enabled but not currently doing any fading. No-one really needs to think about the number when there’s virtually no CPU in use.

Also, see this:

What is the processing speed indication? [Answered]

From the DSP FAQ: Note that Roon currently runs the DSP engine on one CPU core per zone–so this reflects the load relative to consuming a full core. “2.0x” means you’re using 50% of one CPU core to play music in this zone. Currently, I"m playing a local copy of the Mac’s Rumors (24/96) and upsampling to 24/192. I’m getting 32.2x which means, if I am understanding the FAQ correctly, I’m using (100/32.2) = 3.1055 or 3.1% of one of my 8 cores to do the upsampling. Is this correct? If so, the…
