Here is my issue. When Unraid is running mover, downloading files "typically at about 20MBs", and Plex is processing those files I sometimes get periods of buffering every 10 seconds or so.
I understand this is likely an IO/storage speed/parity write operation issue.
Is there anyway to optimize my setup to handle this better? It seems like even with all of these operations going on at the same time that my rig is not even breaking a sweat. None of the drives appear to be at their max IO or read/write capabilities, but yet I still get these times where Plex buffers hard.
Here is a screenshot of my drives while a move is occurring which also just seems slow in general. I am to the point where I am considering just moving the media to a non parity protected pool in hopes it stops the buffering issues.
In the picture my Cache ssd is for appdata, cache_nvme is for some vm's and servers I run sometimes, and Cache_ssd is my download folder cache drive.
I am hoping someone can help me understand what is going on and maybe the steps you would take to diagnose the bottleneck. I am at the point that maybe I just move media to a pool and out of the parity protected array OR maybe I try a more traditional raid setup for better performance.
Here are my server specs:
