I'm really losing my mind trying to figure out why my Jellyfin instance runs so frickin hot. I have 16 Xeon 5-2680 @ 2.50GHz procs assigned to it with 128G of memory. When watching an H264 encoded movie, this thing runs at 95% CPU and never comes below about 85% memory usage. Its a VM and the Jellyfin instance is running in the official container that is up to date. Something has to be wrong here because the exact same media file played on Plex from the exact same VM doesn't even break a couple of percent of CPU. I play everything without transcoding. And the behaviour is the same via Roku client or Webclient. All of this power and I can only just play 1 stream at a time. And the behaviour is the same even if I am playing the file right off the local filesystem.
This is the docker compose:
if anyone could offer any advice, I'd really appreciate it.
