Chunk & Farm Limits
Server-wide limits exist to protect performance (TPS) from overloaded farms and machine stacking.
Per-Chunk Entity Limits
| Entity Type | Max per Chunk |
|---|---|
| Hostile mobs | 20 |
| Passive mobs (animals) | 15 |
| Item drops | 40 |
| Minecarts | 5 |
| Boats | 5 |
Hopper & Machine Limits
| Item | Max per Chunk |
|---|---|
| Hoppers | 16 |
| Slimefun Electric machines | 8 |
| Slimefun multiblock machines | No hard cap, but must not overlap |
| Redstone clocks (active) | Throttled automatically past 8 |
Farm Spacing Rules
- Mob farms must be spaced at least 32 blocks apart (center to center) to avoid mob-cap starving neighboring farms.
- AFK fishing/farm rigs must not exceed 1 hopper line per chunk boundary.
- Auto-crafters and cargo networks pulling from the same chunk share that chunk's hopper limit.
Checking Limits
/chunkinfo (if installed) shows current entity/hopper counts for the chunk you're standing in, useful for diagnosing lag before it's reported.
