My plex server on Ubuntu server 22.04.2 was buffering too much so I checked my processes with the top command and it showed this.

I don't know what it is. Can I stop it? It's using 20% of my CPU.

    PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND
   5751 root      20   0       0      0      0 I  20.9   0.0   3:47.05 kworker/1:3-events

    The Plex Media Server can use up quite a bit of CPU and GPU while playing movies or TV shows. Basically anything that needs transcoding can do it. Mine can go anywhere from 2% to 30%. – Terrance Apr 28 '23 at 04:07
  • @Terrance haha when my CPU is transcoding it goes to 98% it makes me worried cause the fan speeds don't change but I am working on it. i was wondering if you can tell me how can I set my plex server so that It uses my 2Gb and GPU for transcoding. Will it help? thanks already – NOOB Apr 28 '23 at 04:50

    Better transcoding comes from a better video card that supports it. Also, more RAM would help the system out a lot. You might want to read through https://support.plex.tv/articles/115002178853-using-hardware-accelerated-streaming/ – Terrance Apr 28 '23 at 04:55
