About this project
What does Just Enough Freezes (Forked) add?

Just Enough Freezes stops JEI from freezing your game.
Joining a world and nearly everything related to JEI is basically faster! The gains are super obvious;
In a 432 mod pack, JEI starts up about 4.1x faster.
This mods a genuine JEI optimization mod, not scrapped around from other optimization mods (or vibe coded). This is the original one and its pretty stable.
Forge 1.20.1 | Client side | JEI 15.x
Features

- JEI's search uses all CPU cores instead of one.
- Item tooltips are read the same way as well!

- Items with thousands of recipes or uses open without locking up because they only build the page you're looking at.

- JEI makes an anvil and grindstone recipe for every item, enchantment and level. In big packs that's hundreds of thousands of entries nobody looks up.
- If you want them back, there's a toggle in config file.

- Brewing recipes are found through an index instead of searching everything over and over.
- Potions it already went through don't get brewed again on every pass.
- It double checks itself against JEI so nun causes problem

- Works on stable and beta 1.21.1, including the newest ones.
- If your JEI already does something itself, that part of the mod just stays out of the way.
- Client side only. Servers don't need it.

- Everything has an on/off switch in
config/fastjei-client.toml. - Your log shows how long each step took, if you're curious.. I am.
