Server Version#: 1.23.3.4707 Player Version#: 1.33.0.2444-a220eae4 I’m seeing a whole load of SLOW QUERY errors in the PMS logs. Media is on unRAID array, Plex Metadata/DB/Config is on a dedicated SATA SSD, not unRAID cache drive. Using official Plex container. Jun 28, 2021 14:36:12.934 [0x15513…

Overseer running in Docker but that has always been installed. I run 2 servers (one on NAS (Synology) and other on Shield) I just find PMS on NAS extremely sluggish mostly shows up as Unavailable. Only indexed large Music folder (approx. 30k albums). What gets me is PlexMediaServer process is always…

about. 6 hours ago I downgraded to image: plexinc/pms-docker:1.23.6.4881-e2e58f321 And I see a lot fewer slow query messages (which is not a very good indicator, there might just be less debug info in the codebase calling that). But more importantly I see less occurrences of the scanning stalling. …

I’ve came across this issue it seems that when you have large collection of movies/ tv shows the sqlite database can’t handle the amount of transactions with default cache size. I was able to fix it by increasing the “PRAGMA default_cache_size” on the plex db. depending on your setup, if you’re on…

It’s a very large Music only library on a Synology NAS (Linux) so I’ll give that a go…

Is the cache size dependant on RAM (my NAS is 4GB) or how do I determine the right cache size? PMS on the Synology DSM 7 is located at “/var/packages/PlexMediaServer/home/Plex Media Server/Plug-in Support/Databases/com.plexapp.plugins.library.db” sqlite3 is at usr/bin

Yeah the cache size is depending on how much ram you have :slight_smile: I have 16GB in my server and I only gave mine 600 MB it made a huge difference.

Do you believe Plex uses default_cache_size? I don’t think it does, and I don’t believe setting default_cache_size in the .db file is effective. I’ve observed that Plex Media Server explicitly sets cache_size when opening database files, overriding and ignoring any default_cache_size set in the .db…

you mind showing me a screenshot or a stacktrace of this explicitly being set by Plex? because when I check the schemas it’s set to the value that I applied?

oh also one more thing might help is in increase your folder watch size

Linux Tips

This might help out as well, since the collection is music
