The simplest way to boost server performance and eliminate lag.
The simplest way to boost server performance and eliminate lag.
SyncBoost is not just another "lag clear" plugin; it is a comprehensive, professional-grade performance engine. Re-engineered for maximum efficiency, SyncBoost targets the root causes of server degradation—identifying CPU bottlenecks, memory leaks, and excessive entity overhead—allowing your server to sustain high player counts without compromising gameplay quality.
[!IMPORTANT]
SyncBoost is optimized for modern Minecraft infrastructure (1.20.5 - 1.21.x) but also fully supports legacy versions (1.17.1 - 1.20.4).
Recommended Java 21, minimum Java 17.
| Requirement | Version |
|---|---|
| Java | 17 or newer (Required) |
| Minecraft | 1.17.1 - 1.21.4+ |
| Server Software | Spigot, Paper, Purpur, Pufferfish, Folia, or compatible forks |
SyncBoost is modular by design. Enable or disable features as needed via the in-game GUI or modules/ config files.
| Module | Impact | Description |
|---|---|---|
| MobAiReducer | 🔴 Very High | Optimizes creature pathfinding and AI behavior. Essential for farm-heavy survival servers. |
| EntityLimiter | 🔴 High | Enforces limits on entity counts. Features Smart Mob Cap effectively balancing mob density based on server TPS. |
| LagShield | 🔴 High | Active monitoring that triggers safety measures (e.g., pausing spawners) when TPS drops critically. |
| ExplosionOptimizer | 🔴 High | Efficiently handles TNT and crystal explosions to prevent physics ticks from stalling the main thread. |
| ChunkAnalyzer | 🔴 High | Scans and identifies problematic chunks with high entity/tile entity counts. Features interactive GUI with teleportation. |
| WorldCleaner | 🟡 Medium | Periodically removes ground items. Features an "Abyss" system for item recovery via /abyss. |
| RedstoneLimiter | 🟡 Medium | Detects and suppresses rapid-pulsing redstone clocks that cause TPS drops. |
| VehicleMotionReducer | 🟡 Medium | Optimizes boat and minecart collisions, movement logic, and removes mineshaft clutter. |
| AbilityLimiter | 🟡 Medium | Limits rapid Trident/Elytra usage to prevent excessive chunk loading. |
| HopperOptimizer | 🟡 Medium | Reduces hopper tick rates and optimizes item transfer logic to minimize lag. |
| InstantLeafDecay | 🔵 Low | Makes leaves decay instantly when trees are cut, reducing entity processing. |
| ConsoleFilter | 🔵 Visual | Regex-based filtering to keep your server console clean and readable. |

SyncBoost is a forked and modernized continuation, designed to support the latest Minecraft infrastructure while respecting the legacy of the original project.
SyncBoost requires minimum Java 17 and recommends Java 21 for optimal performance. Java 21 offers significant performance improvements for modern servers.
Which Minecraft versions are supported?SyncBoost supports Minecraft 1.17.1 - 1.21.4+. Legacy versions (1.17.1 - 1.20.4) are fully supported, and 1.16.5 is available via manual build configuration.
Is SyncBoost compatible with Folia?Yes! SyncBoost fully supports Folia's regionized multithreading. All optimization modules are compatible with Folia's architecture and use proper thread-safe operations.
What server platforms are supported?SyncBoost works with Spigot, Paper, Purpur, Pufferfish, Folia, and any compatible fork. Paper or higher is recommended for best performance.
Will SyncBoost conflict with other optimization plugins?SyncBoost is designed to work alongside other plugins. It integrates seamlessly with Spark for profiling and stacker plugins like WildStacker, RoseStacker, and UltimateStacker.
How do I recover accidentally cleared items?Use the Abyss feature! Items cleared by WorldCleaner are temporarily stored and can be recovered using /abyss command within a configurable time window.
