Essentially, when the protocol is still enabled globally, the unit will attempt to participate in the Spanning Tree algorithm. With that in mind, it will advertise it's parameters via a mulitcast that is flooded throughout the entire network. Disabling Spanning Tree globally will prevent these BPDUs from being sent, thus reducing the small overhead generated by the protocol. Ideally, unless you are experiencing issues related to Spanning Tree, enabling Fast Link / Edge Port should be sufficient.
Depending on your topology, it may be beneficial to leave to protocol enabled as another fail-safe measurement to prevent a network outage.

Addition:
This is in regards to STP on a per port basis.
