Hi Guys. I am the author of Audiophile Linux OS. I don’t know if you heard
of it, but it’s a free operating system based on Arch Linux. I am now building
the 4th release and I am thinking it would be nice thing to offer AP-Linux
users an option to install Roon server. I tried it and it’s working out of
the box. But there’s one problem. After selecting my DAC and setting up the
zone, the CPU usage starts to spike. I doesn’t matter if you play the music
or don’t, the Roon server process is always at 30% of CPU usage.
PID USER PR NI VIRT RES %CPU %MEM TIME+ S COMMAND
553 root 20 0 1187.1m 143.8m 32.5 1.8 0:47.68 S Main
And this is the process that is doing it:
/opt/RoonServer/Mono/bin/RoonAppliance --debug --gc=sgen --server RoonAppliance.exe -watchdogport=37999
I am using custom 4.8.11 realtime kernel.
I don’t know if it’s a bug of some kind, or something else. But our users are
very demanding when it comes to software and hardware. They are building
the best PC machines for music. Everything has to be silent. SSD disks and CPU’s
without fans. Giving that Roon server software is taking so much CPU power even
when it’s idle, it would be an overkill to install Roon server on some silent PC’s
or devices without fans. Not to mention how CPU usage is critical for sound
processing. Can you help me identify what’s the problem?
Thanks and nice regards,
