Basically, any docker path starting with /mnt/user as your docker config locations are a recipe for performance issues.Ĭhanging the default docker path to /mnt/cache/appdata/Plex (or /mnt/diskX/appdata/Plex if you're not using a cache drive) will bypass the Unraid FUSE filesystem and ensure your dockers read/write directly to your disks so you get full read/write speeds.ĭoing this simple change resulted in a massive performance gain. While this works, that default path makes any reads/writes go through the Unraid FUSE filesystem which kills performance. About 2 weeks ago I finally solved it and thought I would post it for those of you with similar issues.īy default, the Unraid Plex docker is configured to store it's database and all your library metadata using the path /mnt/user/appdata/Plex. I tried everything to fix this, even working with the Plex team and still couldn't solve the issue. While Plex has been serviceable for me during that time, I suffered all sorts of random performance issues where libraries were slow to load, recommended tabs would randomly time out or take 30-45 seconds to load, going into tv shows would take 5+ seconds or more to show episode thumbnails, movie collections would take forever to open and Plex itself would lock up and go unresponsive during library scans etc. I've been running a Plex server for a few years via Unraid.
