Resenha Party — Performance & Stability Update

🔥 The Problem

A server was experiencing critical performance issues: constant "Can't keep up!" warnings (21 in a single hour), lag spikes of up to 17 minutes, 159 hostile mimics alive simultaneously, memory leaks causing +110MB of unreleased RAM, and 10.5GB full backups running mid-gameplay. This update addresses all of these issues.

---

⚡ Performance — ServerCore

• Enabled Activation Range — Entities far from players are no longer fully ticked, massively reducing CPU load
• Enabled Dynamic Performance — The server now automatically adjusts mob caps, view distance, and simulation distance based on current MSPT
• Enabled Villager Lobotomization — Villagers trapped in 1x1 spaces now tick at reduced intervals instead of wasting server resources
• Enabled Breeding Cap — Animal and villager breeding is now capped at 32 per type within a 64-block radius, preventing entity explosion from uncontrolled farms
• Enabled Fast Biome Lookups — More efficient mob spawning calculations
• Enabled Cancel Duplicate Fluid Ticks — Removes redundant fluid tick processing

⚡ Performance — C2ME (Chunk Engine)

• Enabled GC-Free Chunk Serializer — Reduces memory allocations when saving chunks, lowering GC pressure
• Enabled Density Function Compiler — Compiles worldgen functions to JVM bytecode for significantly faster terrain generation
• Enabled Low Memory Mode — Aggressively unloads unused chunks to combat memory leaks

⚡ Performance — ModernFix

• Enabled Dynamic Resources — Resources are now loaded on-demand instead of all at once, reducing memory footprint
• Enabled Ingredient Item Deduplication — Deduplicates recipe ingredients in memory, saving RAM

⚡ Performance — AllTheLeaks

• Enabled Ingredient Deduplication — Reduces memory usage from duplicate recipe data
• Enabled Skip Ticking Unloaded Flux Networks — Prevents unnecessary ticking of unloaded network blocks

⚡ Performance — FTB Chunks

• Reduced max claimed chunks from 500 → 50 per player
• Reduced max force-loaded chunks from 25 → 5 per player
• Force-loaded chunks remain active 24/7 and are one of the heaviest server loads — this change alone significantly reduces idle server strain

🗺️ Worldgen — Artifacts

• Reduced campsite generation from 40 → 5 attempts per chunk — the previous value was spawning massive amounts of hostile mimics
• Reduced mimic chance from 30% → 10% — previously caused 159+ mimics to be alive simultaneously, consuming excessive tick time

💾 Backups — SimpleBackups

• Changed backup type from Full → Incremental (Modified Since Last) — backups were previously 10.5GB taking 2.5 minutes of heavy disk I/O mid-gameplay
• Increased backup interval from 2 hours → 4 hours — reduces I/O interruptions during play sessions

🧹 Cleanup — Removed Orphan Configs

Removed configuration files for mods no longer in the pack:

• PacketFixer — was conflicting with Connectivity mod via mixin overlap
• Carry On — was causing ServerPlayer memory leaks (24 player clones vs only 5 logouts detected)
• Corpse, CorpseCuriosCompat, Selling Bin, Apothic Spawners
• Removed 5 orphan config directories: arsomega, ars_scalaes, ars_trinkets, toomanyglyphs, rpg_series

🖥️ Server Deployment

• Added server-setup.sh script for dedicated server setup
• Removes client-only mods (Sodium, Iris, Dynamic FPS, etc.)
• Configures max-tick-time=-1 to prevent watchdog crashes
• Optimizes view-distance and simulation-distance

Note: A server restart is required for all changes to take effect. Existing worlds are fully compatible — no world reset needed.
