Virtual Machine requirements/recommendations for PMS

General Discussions
1

Hello,

I currently deploy Plex Media Server (PMS) as a Docker container on a Virtual Machine with Proxmox VE as the Hypervisor (KVM). The Node has 2 virtual cores and 2GB of memory.

I notice performance issues – especially with Live TV and Recordings from my HDHomeRun Quatro.

I do notice significant high CPU utilization on the running container with my Prometheus+Grafana monitoring.

My question is:

What is the minimum and recommended requirements for running Plex Media Serve r (PMS) in a virtual environment to get acceptable to decent performance.

Thanks!

cheers
James

The defining factor will be, do you have clients that can play MPEG2 streams, if not then the CPU and/or GPU will have to transcode for you. If you have a recent core Ix-xxxx cpu, it might perform better with a LXC install. Plex likes high single core performance for live tv, find out your passmark, for a 20Mbps 1080 stream you would need close to 3000. DVR shouldn’t use that much, make sure you are using VIRTIO for network and disk.
