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.

On the switch side (Juniper) the physical interface flaps. There's nothing
in logs/dmesg.
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.
