Are you using auto-negotiation? I assume so, since auto-negotiation cane take that long or longer to link. Depending on what you are linking to can also make a difference. If you want to speed up the link time, you can hard set the speed and duplex on both the NIC and the device it connects to. That will speed up the "link up".
