However for the future reference there is entry to priority security that bypasses the normal line from downstairs general area, you can either enter from KLM SkyPriority checkin area or from the Privium lounge side when you turn right after getting out. Since the reported delay for priority was actually getting to the priority scanners, I assume this would have been a lot faster.
