There seems to be a tactic to speed up the linkable portal list build time. If you put the possible linkable keys from that portal into a capsule excluding your target portals, the overall scanning time decreases giving you more time to complete the linking action. So if you have little time to link from a portal you should prepare yourself by putting possible unwanted target keys into a capsule before arriving to that portal.

This tip has been approved by field trials by many players.
