Obscura's Simple Storage

Welcome to Obscura's Simple Storage—the definitive, high-performance vanilla-plus storage network solution for modern Minecraft modpacks.

Have you ever built a massive storage network only to experience severe server TPS drops, memory leaks, or client-side stuttering when you open your crafting terminal? We fixed all of that.

Obscura's Simple Storage is a heavily modernized, hyper-optimized overhaul of the classic Tom's Simple Storage. We tore down the engine and rebuilt the core mechanics to handle monumental amounts of items and containers with zero lag. Coupled with a gorgeous, high-quality, built-in texture redesign, this is the ultimate way to manage your items.

What Makes Obscura's Simple Storage Better?

We implemented over 80+ specific architectural optimizations and bug fixes to make this the most performant simple storage mod available:

Server TPS & Performance Overhaul

The Slot Scanner Rewrite: We completely removed the brutal O(S²) inventory scanning pattern, replacing it with a lightning-fast O(S) iterator-based system.
Hash-Based Filtering: The old linear filter scans have been entirely rewritten. You now benefit from O(1) hash-set lookups on Polymorphic and Tag-based item filters.
Inventory Hopper Tick Reduction: We slashed the baseline idle tick cost of Inventory Hoppers by ~93%, preventing them from crippling server performance when placed in bulk.
Smart Cable Networking: Rebuilt the cable network logic to use per-network invalidation rather than global rebuilds, saving immense calculation time on chunk loads/unloads.

Client FPS & GUI Fixes

Zero-Lag Terminals: The GUI rendering loop was rewritten to eliminate roughly 21,600 memory allocations per second. Your frames will no longer drop when searching through massive networks.
Instant Terminal Sync: Fixed the dreaded terminal desync bugs. No more waiting—terminals now perform an immediate first sync when opened, and search inputs are properly debounced.
Scrolling & Rendering Math: Fixed native UI scrolling math bugs that caused jitter in huge inventories.

Stability & Memory Security

Memory Leaks Patched: We identified and fixed several critical WorldStates memory leaks, stale cache accumulation, and null-value build-ups that degraded server performance over time.
Thread Safety: Rebuilt critical data structures with ConcurrentHashMap and volatile generation flags to prevent random storage network crashes under heavy multithreading environments.

Fresh Modern Visuals

Not only does it run flawlessly, but it also looks incredible. We have integrated beautiful, custom-designed, high-resolution textures natively into the mod. From the cables to the terminals and filters, your storage room has never looked more professional.
