EMI Accelerator
Caches the EMI item stack list to disk and defers search index building to a background thread, drastically reducing EMI reload time.
Overview
Every time you join a world or reload resources, EMI rebuilds the entire item stack list and search index. For modpacks with a large number of mods, this process can take tens of seconds, and the game UI freezes completely while the search index is being built.
EMI Accelerator solves this problem with the following optimizations:
- Stack Caching: Serializes
EmiStackList.stacksto JSON and caches it to disk on the first load. Subsequent game launches skip the full reload (around 130ms compared to ~40 seconds). - Deferred Search: Defers
EmiSearch.bake()to a background thread, eliminating roughly 10 seconds of UI blocking. - Auto Refresh: Automatically updates EMI search results once background indexing finishes, with no manual re-input required.
Usage

How It Works
- EMI tag sync triggers →
EmiReloadManager.reload()→ReloadWorker.run()starts - Check if the cache exists and is valid (SHA-256 mod list hash verification)
- Cache hit: Deserialize stack list directly → skip full reload → build search index in background → complete
- Cache miss: Proceed with normal EMI reload → asynchronously write cache after completion
- Automatically refresh the EMI UI after search build finishes, showing
[EMI Accelerator] Search Ready
