Performance Issues/organization advice

Hello! Long time user first time poster! First I want to say I do love the apps for MacOS and iOS, I've been reading comics on my iPad for years and generally it's amazing! However, I'm starting to run into issues around performance of library updates on YACReader Library, as I have a very large collection of comics.

Here's my setup: Mac Mini M2 running YRL connected via wifi to my home network. Home network also has a Synology NAS hard wired to the network that houses my collection. My Comics libary is structured like this:

Lirbary 1 (Publisher 1)
> Series 1
> Series 2
.
.
.
>Series N

Library 2 (Publisher 2)
> Series 1
.
.
.>Series N

So I have 6 total Libraries in the server, but a couple of them in particular have 1k+ series sub folders, and in total maybe 20k+ individual comics? honestly I don't know, I've never counted! But it's massive. When I try to update the publisher libraries (even when only adding a handful of new titles) the system just hangs, sometimes crashes, or takes a very long time to update. The smaller libraries usually update just fine, but the big ones never seem to work the first time.

Do you have any advice? Am I just out of luck since my collection is so large? Or is there a better way to organize my libraries?

Thanks in advance!

You can run YACReaderLibraryServer directly in your NAS using the official Docker image, then you can perform the updates locally without hitting the network. You can still use YACReaderLibrary for browsing and updating metadata, the iOS app can connect directly to the NAS.
