Major performance fixes for Refined Storage in 1.20.1 & 1.12.2
Refined Storage Mixin is a performance-focused addon for Refined Storage that reduces server lag in large networks.
- Load rescan – rescans after controller load so cables like EnderIO conduits get detected.
- Conduit placement fix – rescans after placing EnderIO conduits, since an immediate rescan is too early.
- EnderIO RS fix – stops warnings and restores compatibility with EnderIO's RS conduits.
- EnderIO conduit typed backup – prevents EnderIO conduit data from being lost on world reload.
- EnderIO node unify – fixes EnderIO conduits being tracked as two objects after reload.
- RebornStorage crafter fix – fixes multiblock crafter GUI delays, validation, and error messages.
- Damageable input reuse – lets autocrafting reuse damaged tools instead of always crafting new ones.
- Crafting crash guard – stops a broken autocrafting task from crashing the server.
- Grid resync – fixes open grids showing stale or missing item lists.
- Safe data saving – fixes disks wiping to 0/0 after a server restart.
- Skip unloaded – prevents rare deadlocks from touching unloaded chunks.
- Wireless dimension lock – stops wireless items/transmitters working across dimensions from their linked network.
- Throttle – runs full network updates every N ticks instead of every tick.
- Bypass fast nodes – lets busy nodes (importers, crafters, etc.) update every tick instead of throttled.
- Dynamic node sleep – lets bypassed nodes idle down when they have no work.
- Dynamic crafting bypass – lets the crafting manager update every tick only while jobs are active.
- Lazy energy – recalculates network energy usage only when the graph changes.
- Hashset optimize – uses plain HashMap/HashSet instead of concurrent versions in single-threaded contexts.
- Connected node tick optimize – skips ticking nodes that aren't connected to a network.
- Storage cache debounce – rebuilds the item/fluid list once instead of once per storage block reconnecting.
- Crafting rebuild debounce – rescans autocrafting patterns once instead of once per crafter reconnecting.
- Graph rescan coalesce – merges multiple rescans triggered at once into a single rescan.
- Tracked insert index – speeds up matching returned items to the right crafting step.
