Recommended starting value

The default settings are good enough for most servers, so you can start with these:

wake-up-inactive:
  animals-max-per-tick: 4
  animals-every: 1200
  animals-for: 100
  monsters-max-per-tick: 8
  monsters-every: 400
  monsters-for: 100
  villagers-max-per-tick: 4
  villagers-every: 600
  villagers-for: 100
  flying-monsters-max-per-tick: 8
  flying-monsters-every: 200
  flying-monsters-for: 100
villagers-work-immunity-after: 100
villagers-work-immunity-for: 20
villagers-active-for-panic: true
tick-inactive-villagers: true

If villagers are a particular problem for lag:

wake-up-inactive:
  animals-max-per-tick: 4
  animals-every: 1200
  animals-for: 100
  monsters-max-per-tick: 8
  monsters-every: 400
  monsters-for: 100
  villagers-max-per-tick: 1
  villagers-every: 900
  villagers-for: 100
  flying-monsters-max-per-tick: 8
  flying-monsters-every: 200
  flying-monsters-for: 100
villagers-work-immunity-after: 100
villagers-work-immunity-for: 20
villagers-active-for-panic: true
tick-inactive-villagers: false

If you’re trying to greatly reduce entity-related lag spikes on your server, try these:

wake-up-inactive:
  animals-max-per-tick: 2
  animals-every: 1200
  animals-for: 100
  monsters-max-per-tick: 2
  monsters-every: 400
  monsters-for: 100
  villagers-max-per-tick: 1
  villagers-every: 2000
  villagers-for: 400
  flying-monsters-max-per-tick: 2
  flying-monsters-every: 200
  flying-monsters-for: 100
villagers-work-immunity-after: 120
villagers-work-immunity-for: 20
villagers-active-for-panic: true
tick-inactive-villagers: false

What is an inactive entity?

An inactive entity is just an entity that is outside of its activation range, meaning it won’t tick (i.e., it won’t perform any actions, AI, or movement) until it is ‘woken up’.

What does wake-up-inactive do?

Inside the main wake-up-inactive section, we have three main types of options:

• *-max-per-tick
• *-every
• *-for

*-max-per-tick

The max-per-tick option for each entity type (animals, monsters, villagers, flying-monsters) tells the server the maximum number of inactive entities of that type that can be woken up in a single server tick.

For example, if animals-max-per-tick is set to 4, the server will wake up up to 4 inactive animals per tick.

*-every

The every option for each entity type specifies the interval (in ticks) between each wake-up attempt for that entity type.

For example, if monsters-every is set to 400, the server will attempt to wake up inactive monsters once every 400 ticks (20 seconds).

*-for

This option specified the amount of time (ticks) that the entity will be woken up for before ‘going back to sleep’.

For example, if villagers-for is set to 100, the server will wake up inactive villagers for 100 ticks (5 seconds) before putting them back to sleep.
