lazyyyyy
by settingdust
Lazyyyyy delays loading work that a Forge game does not need at startup, so large modpacks reach the title screen sooner.
What it does
Most of the mod's changes are asynchronous and lazy loading. Work that is not needed right away, such as parts of the mixin config, image resources, sound events and entity renderers, is postponed until the game actually uses it. The goal is that unnecessary logic no longer blocks launch.
Lazyyyyy is built for large packs, where startup time grows with the number of mods. It trades CPU time for memory and disk by building a manifest index, so a lookup can skip scanning every jar. The author describes the function only; no startup figures are given.
Installation needs Forgified Fabric API and Kotlin for Forge. The mod is published for Forge only, for 1.20.1, with 0.14.19 as the latest file. It runs on the client or the server, and neither side requires it. Its source code is public, and it is released under the Creative Commons Attribution Share Alike 4.0 license, so it is not open source.
Key features
Faster mixin config loading
Mixin configs are read more quickly, but the feature only works with Sinytra Connector or Mixin Booster present on Forge.
Lazy YACL image loading
Image resources used by the YACL configuration screen are loaded asynchronously, only when they are about to be drawn.
Faster manifest lookup
A manifest index lets the game find mod manifests quickly, since each manifest must sit inside its own mod's jar.
Lazy entity renderers
Entity, block entity and player renderers are set up on demand instead of at launch.
Asynchronous sound loading
Sound events from Entity Sound Features load in the background and begin playing only once they are ready.
Compatibility

Use cases
Large modpacks
Packs with many mods gain the most, since the postponed work grows with the number of installed mods.
Who it’s for: Players who run large modpacks and server owners who want quicker startup. Players with a small mod list will notice little change.

You know, we are lazy. Of course, both the game and computer are lazy as well. This mod here for let them be lazyyyyy. Mainly through asynchronous and lazy loading so that unnecessary logic doesn't prevent the game from launching. Take advantage from index for trading the cpu time with the memory and disk.
