Why would disabling STP on the switch *shorten* the amount of time it takes 
for the port to come up?  At least on Cisco switches, it takes ~45 seconds 
for the switching topology to converge with STP disabled.  Shorter periods 
if you enable portfast or uplinkfast.

Might be, you have spanning tree enabled on the switch port and when the 
interface "flaps" it needs time to converge. Disable spanning tree on the 
port and the reset will be very short.
