About this project
What does Create:LazyTick add?
Create: Lazy Tick ⚙️
A highly optimized mod based on Lazy Tick, designed to significantly reduce the workload of Create components and their constant usage 🔄. This allows servers to support 2-3 times more Create power production lines compared to pure Create!
🔧 Core Optimizations
🧱 Logistics Components
- Belt / Funnel / Chute / Depot
- 50%–95% reduction in idle overhead
- 40%–80% reduction in dynamic extra workload
- Significant gains in large-scale storage and filtering systems
🏭 Processing Components
- Mechanical Crafter / Mechanical Mixer / Mechanical Saw / Basin
- Introduces recipe caching mechanisms
- Performance improvement scales with recipe count
- 70%–95% reduction in active workload
- In extreme cases, workload drops from ~300µs to ~2–10µs
🤖 Interaction Components
- Mechanical Arm / Deployer
- Reduces frequent checks and repeated searches
- 20%–60% workload reduction
- Greater gains when interacting with Belts
🌊 Fluid System Optimization
- Global fluid ticking reduced to 1/k of vanilla (default: 1/5)
- Multiplier configurable via config
- Significant improvements in large pipe networks
📊 Real-World Performance
In live server testing environments:
- Supports 2–3× more fully active production lines
- Semi-idle structures can scale beyond 5× vanilla capacity
- Optimization strength increases with larger recipe datasets
⚠️ Important Notes
- Reduced tick frequency may cause slight animation delays (configurable)
- Some logic checks have been modified; contraptions relying on strict vanilla tick synchronization may require adjustment using the LazyTick Clock
- Always test and back up your world before deploying to production servers
