I have a general question of whether Plex has any limitations with the size of the library it can support and if there are any tweaks I need to make as it grows. I have library on a Synology NAS (RAID 5) that is about 95% full totaling 57.5TB. Plex is running in a Docker container and appears to be …

GitHub - ChuckPa/PlexDBRepair: Database repair utility for Plex Media Server databases - This tool can help optimize your setup and is easy to use so might be a good place to start. :slight_smile: I do believe having 95% full on a RAID setup can diminish its performance as well. I don’t remember th…

If you’re running PMS on your NAS, take it out and install it on better hardware. Just use your NAS for storage.

The size of the media files doesn’t matter that much. It’s their number that is more important.

All great suggestions and thanks. My NAS doesn’t transcode very well so I have to upgrade.

I found this thread because I think I just found the “limit” for my setup, and I was hoping to find answers, too. For the sake of discussion, let’s say that I created 150,000 test “movies” and added them to a new library. The all have the IMDB id in the filename, and I gave them all accompanying J…

Hold your verdict until the first nightly server maintenance period has passed. Also, first check if you are affected by Library.db size more than doubled in latest version

My server should be settling down today… how will I know that the server maintenance has been performed? For anyone who’s interested, I added 165,000 test files. The single library I added them to still will not load. Without removing that library, I created 5 new libraries, and added roughly 33k…

I think my DB is as self-optimized as it’s going to get. I’m still having the same results… the large library will not open, and I seem unable to edit any collections. I can still open the smaller libraries without error, most of the time. I bumped the database cache up to 8GB, but that didn’t se…

[image] scottl2k: I bumped the database cache up to 8GB That is not a file cache. Leave it at default size and only increment it in a few MB steps. Measure performance. If there is no improvement, take back the last increase.
