Enhanced Hoppers! - Accelerated Hoppers for Minecraft
This mod provides simple commands to configure hopper operations in your world. With them, you can significantly speed up item transfer through the hopper system.
Two main commands are available:
/hopperspeed
/hoppertransferrate
The mod only needs to be installed on the server side. However, if you play in singleplayer mode, you need to add it to the client side as well for proper operation.
