Pipez Optimizer

by Saku_rain

Pipez Optimizer is an unofficial add-on to Pipez that rebuilds how pipes move items, fluids and energy so servers spend less time on repeated inventory checks.

What it does

Pipez Optimizer replaces parts of the Pipez transfer logic. Round Robin distribution is rebuilt around a mathematical splitting method instead of repeated simulated extractions, and the other distribution modes are improved mainly through faster filter checking. Pipes that fail to extract or insert, for example because the target inventory is full, enter a sleep state rather than rechecking every tick, and they remember the last inventory slot they worked with so large inventories are not scanned again from the start. The add-on also gives server owners a custom extraction frequency feature that can be switched off for item, fluid or energy pipe types through a configuration file.

The mod adds three endgame upgrades, the ATM Upgrade, the Vibranium Upgrade and the Unobtainium Upgrade, which provide very high transfer rates and capacity boosts for heavy modpacks. Crafting them requires the Allthemodium mod, while installed alternative recipes become available automatically when it is absent. A minimalist configuration panel is added to the native Pipez screen. Pipez is required, and Ender IO: Evolution is optional. The mod runs on Forge and NeoForge for 1.19.2 – 1.21.1, with builds for 1.19.2, 1.20.1 and 1.21.1. It is not open source and is released under All rights reserved.

Key features

  1. Sleeping pipes

    Pipes that cannot extract or insert pause and wait instead of repeating useless checks each tick.

  2. Slot memory

    Pipes remember the last inventory slot they interacted with, so large inventories are not scanned from the beginning.

  3. Optimized distribution

    Round Robin mode uses a mathematical splitting method, and other modes gain faster filter checking.

  4. Endgame upgrades

    Three new high-tier upgrades add extremely high transfer rates and capacity boosts for pipes.

  5. Per-type frequency control

    Server owners can disable the custom extraction frequency for item, fluid or energy pipes in the configuration file.

Yes. Servers that run it need every player to install it too.

Are the new upgrades available without Allthemodium?

Their normal recipe requires the Allthemodium mod. When it is not installed, alternative fallback recipes become available automatically.
