Performance Action Items

[richardhendricks]

Todo list for GTNewHorizons/GT-New-Horizons-Modpack#5163

• Implement recipe cache for worktable, since it has to scan the whole recipelist. Recipe cache cannot be fixed size, since worktable may find multiple items to add.
• Move found items to the front of the recipelist, if they are not within the first 500.
• Verify shapeless recipes properly working
• Look at how the RecipeUtil is called multiple times, and analyze the causes - is it updating the ghost image? Why is it doing it between every craft? Can it update it after the shift-craft is complete instead of after every step?
• Look at UI behavior when there isn't enough to make. Why does it fill up the whole UI and then remove them? Happens with cobble making stairs.
• Look at crashing behavior when recipe cannot be made due to missing ingredients. Happens with woven cloth when string is available but not cotton. Looks like a stack overflow?

• Look at TiCon crafting station
• Look at AE2 crafting
• Look at vanilla forge crafting - maybe solution here?
• Look at modifying minetweaker scripts, and/or adding feature to put recipe at the front. Can also be done with code.

---

• Create performance debugging tips page. Dynamic debug, sampler, setting up eclipse.

---

• Look at phantom chunk loading/unloading. Dynamic printf might be able to help us determine which chunks are causing it. /sampler loads show also does this. https://www.eclipse.org/community/eclipse_newsletter/2017/april/article2.php Could be related to Glint Weed, monster pathing near a roguelike, monster pathing in general

---

• Look at dynamically re-arranging the recipe map for GT machines as well. Put used recipes at the front. Might help a bit with lag on larger bases/populated servers. Esp. for things like forgehammer.
