If no other switches are going to be placed on a port and only a single client end device, then the following statement can improve link connection establishment speed. This is assuming a Cisco switch. If not a Cisco switch, please provide more details about your environment.
See this <a href=”http://www.cisco.com/en/US/docs/switches/lan/catalyst5000/catos/5.x/configuration/guide/stp_enha.html”>Cisco tech note</a> for more details on spanning-tree portfast:
<i>Spanning-tree PortFast causes a port to enter the spanning-tree forwarding state immediately, bypassing the listening and learning states. You can use PortFast on switch ports connected to a single workstation or server to allow those devices to connect to the network immediately, instead of waiting for the port to transition from the listening and learning states to the forwarding state. </i>
