Is there anything I can do to speed up Kodi's handling of Collections?

[kandykarter]

So, I'm using J4K in Addon Mode, and everything is dialed in pretty much exactly as I want it. Fully integrated into my Kodi skin, etc.

The only remaining problem I have is with Sets/Collections. I make pretty heavy use of my Collections library in Jellyfin using letterboxd-auto-collections to pull themed lists of films due to Jellyfin's lack of "discovery" options to browse a very large library.

Of course, I'm aware that Kodi only allows movies to show in one set at a time, as its Sets interface is designed to really only work with groups of related films (the indiana jones movies, or star wars, etc), which makes the native "Sets" interface basically useless to me. Instead, I have shortcuts mapped to Jellyfin's "Collections" library, which works well enough once it loads, but I'm waiting an average of a minute or so for the Collections library to load in Kodi, then another minute or so to click through into the actual collections themselves.

[Edited to add: this is probably a more general "how can I speed up "Dynamic" library access", as my Music library, which is not synced with Kodi, also takes absolute *ages* to load. I've futzed around with the "Paging" options in the addon settings and it doesn't seem to have had much effect on anything]

Is there any setting I can tweak to speed this up?
