I feel the Inventory Hopper is too slow. I understand this mod serve an early game network storage system so it can't be too good, but I'm running a small server that focus on Vanilla and Tom's Storage helps us to forget about storage system. But my sword with looting III can easily overwhelming 2 Inventory Hopper when I'm at the mob farm, so my suggestion is:
1/ Add a config option to make the faster
2/ Add another hopper that's more advanced i.e can filter the items itself and is faster than the Basic
3/ Add an upgrade module for the hopper.

Thank you!
