Description

NoTick

NoTick is a server-side entity tick optimizer built for large modded Minecraft servers.

Large packs can waste a lot of CPU time ticking mobs, items, and other entities that no player can see, reach, fight, collect, or interact with. NoTick cuts that background work by skipping eligible far-away entity ticks while keeping important gameplay protected.

The goal is simple: less wasted simulation, more tick budget for the parts of the server players are actually using.

Tick Savings Example

NoTick's savings scale with the number of eligible distant entities. If an entity is outside player range and is not protected by a whitelist, claim, raid rule, or active chunk safeguard, its normal entity tick can be skipped.

Eligible distant entities Tick calls skipped per server tick Tick calls skipped per second at 20 TPS 100 up to 100 up to 2,000 500 up to 500 up to 10,000 1,000 up to 1,000 up to 20,000 2,500 up to 2,500 up to 50,000

These are not fake benchmark claims. They show the math behind the optimization: fewer eligible distant entities ticking means less background entity work for the server.

What Stays Active

Players and nearby gameplay [ACTIVE] always ticks normally Whitelisted entities/mods [ACTIVE] protected by config Claimed bases and farms [ACTIVE] protected with FTB Chunks or OPAC Raid-sensitive entities [ACTIVE] protected by raid rules Distant unused mobs/entities [OPTIMIZE] skipped when safely outside range Distant dropped items [OPTIONAL] configurable chance-based ticking

Decision Flow

Entity tick starts -> Player? Tick normally -> Disabled by config? Tick normally -> Whitelisted entity or mod? Tick normally -> Near a player? Tick normally -> In active or claimed chunk? Tick normally -> Raid-protected? Tick normally -> Eligible distant entity? Skip tick

Compatibility

NoTick is designed for modded servers and supports modded entities through normal registry IDs.

Use config whitelists for:

bosses and multipart mobs
scripted or event entities
fake-player-style automation
projectiles or special entities from large content mods
any mod where distant entities must keep ticking normally

If FTB Chunks or Open Parties and Claims is installed, claimed chunks can be treated as protected areas. This is useful for farms, automation zones, and bases that should keep normal behavior while players are away.

Best Fit

NoTick is strongest on:

large modded survival servers
kitchensink packs with heavy passive entity load
SMPs with many bases, farms, and dimensions
servers where distant mobs and items create constant tick cost
packs that need admin-controlled performance safeguards

Important Note

NoTick is intentionally performance-focused and can change behavior for far-away, unprotected entities.

If a farm or contraption must run while nobody is nearby, protect it with chunk claims, active chunk safeguards, entity whitelists, mod ID whitelists, or dimension rules.
