Create: Threaded Trains
by MrJulsen
Create: Threaded Trains moves the railway network calculations of Create onto a separate thread that runs alongside the server tick, so fewer tasks wait in sequence.
What it does
The mod starts the railway network calculations at the beginning of each new server tick, in parallel with the other tasks, and both sides wait for each other before the tick ends so the game stays synchronized. The author reports that this reduces the overall tick time, with the largest gains on big networks; tests on a server with 700+ trains and 200 mods are cited as the basis.
The mod requires Create and Create Fabric as dependencies, so both must be present alongside it. It is server-side only, though it can also run on a client in single-player. Files exist for Fabric, Forge and NeoForge, with game versions 1.18.2, 1.19.2, 1.20.1 and 1.21.1. The mod is open source under the GNU General Public License v3.0 or later.
Key features
Parallel railway calculations
Railway network work runs on its own thread while the rest of the server tick continues.
Synchronized tick end
Both the railway task and the other tasks finish before the tick closes, so game state stays consistent.
Large network focus
The gain is described as most noticeable in networks with many trains, where the railway work is heaviest.
Single-player support
The same code can run on a client when a player hosts a world alone.
