Observed behaviour

When there are many weapons could be used in arcane anvils to combine with scrolls, it lags when looking up in emi/jei to see the recipes in arcane anvil page. And it consumes a lot of memories.

Expected behaviour

jei/emi is used smoothly when looking up recipes.

Steps to reproduce

1.add jei, spellbooks and some mods to add weapons
2.open jei and choose "arcane anvil" page
3.stutter for a while and opened

I have found the potential cause of the memory leak in the "Arcane Anvil View Recipes", it usually sits on the last page:

@ColdTearsYY

How does this memory usage compare to the normal anvil, which also creates a recipe for every weapon per enchantment type per level?

other smithing recipes:

arcane anvil recipes:

Without spellbook mod memory usage range: from 3700 to 5500mb and gc
with mod: from 5900 to 7300mb and gc

although not a leak, it is clearly hogging memory compared to other jei implementations. we'll look into why

This is my whole mods folder test above.
I have already removed emi mod and iron‘s spellbook mod due to the mentioned issue so you could download the file, add mods and test.
@lab3 thx a lot

@ColdTearsYY I'm having trouble reproducing this. Do you have some examples of mods that when added create this issue?

@lab3 Hello, did you had some time to look into the problem? I have a similar Observation.
Maybe Iron's spells 'n speelbooks together with apotheosis is blowing up the memory allocation?
hprof file is generated through spark.

only example to reproduce is the modpack im playing:
https://www.curseforge.com/minecraft/modpacks/sebastian24443-creation

really great mod by the way :)

Having the same problem trying to add Iron's Spells in Prominence II Classic.

Is there any way to disable the JEI recipe for the Arcane Anvil?

I know that you can manipulate recipes with KubeJS, but i didnt found anything about it on google to remove recipes from anvils.
