Block Speed Mod
Block Speed Mod lets a server owner set how many items each Dropper, Dispenser and Autocrafter handles per Redstone pulse.
What it does
The settings are changed per world with three chat commands, and the values take effect immediately and are saved to the world's own configuration. Each save keeps an independent set of values, so one world can run fast automated farms while another stays near vanilla.
Values are stored in blockspeedmod/config.json and can also be edited by hand. A value of 1 returns the matching block type to its default rate. Higher values significantly increase item throughput, so the mod should be used with caution on busy servers. It runs on Fabric for game versions 1.21 – 1.21.11 and requires Fabric API.
Because the environment is server-side only, players join without installing anything and only the server needs the mod. The code is not open source; the license is All rights reserved, while the source code and issue tracker are publicly linked.
Key features
Per-block item rates
Set how many items Droppers, Dispensers and Autocrafters process for each Redstone pulse, with separate values for each block type.
Per-world settings
Every world save keeps its own configuration, so changes in one world do not affect another.
Chat commands
Three commands in chat change the values, and the new numbers are applied and saved at once.
Vanilla reset
A value of 1 returns the matching block type to its default rate without removing the mod.
