I have recently installed ROCK on ESXi virtualization server, and restored my back up after installation. However, the CPU rate for ROCK VM constantly at 60% after that even I am not playing music. Have anyone has encounted similiar issue? any suggestion how to solve this problem?
I run ROCK as VM on top of Proxmox. I had a severe I/O bottle neck which caused high CPU and VMs locking waiting on interrupts. This had nothing to do with Roon. Was ugly. Was my own doing
I run my hypervisor using ZFS as the base filesystem and I didn’t really plan this correctly. ZFS is a beast of a filesystem and I just didn’t do my homework. I’ve since tuned the file system to get it to calm down but a lot of that was some trial / error. I should note that I’m using HDDs only. Again, bunch of self-inflicted wounds here.
After the file system tuning I don’t have any interrupt delays or other issues within the hypervisor. ROCK performs and shows stats just as I’d expect for bare metal.
So… have you looked through the ESXi stats looking for anything that might be suspect?
How many CPU cores and how much memory did you build into the VM? What machine, base clock frequency, is the hypervisor running on? Also, you can mount the ROCK drive to another machine via SMB and look over the logs. That may give clue as to what the system is doing.
