Personal use mod that I've uploaded so others that I play with can use it. You can too if you like this particular module mod out of the billion others.

Performance module = Speed + Efficiency

consumption = 20%
speed = 50%

Compound module = Speed + Efficiency + Productivity

productivity = 10%
consumption = 100%
speed = 35%
pollution = 10%

Compound module combines all 3 vanilla modules, but has the same usage restrictions as productivity modules, namely can only be used to create intermediate products and cannot be used in beacons.

Performance module omits the productivity module, but has no restrictions to its use.

Adds one tiny research item that is available from the start. Almost free to produce.

Completely cheaty, overpowered, and unbalanced as intended.
