HEL T2 main security has been arranged clever way. Only two queues to the regular security with up to 8 screening lines. There are long tables before the actual security lines, where people can spread their stuff on the trays and get belts and jackets off. You can hardly pick a bad line.
Moreover the screening line tables are looooong, so many people can place their items on them as well as pick them out. The process runs very smoothly - as long as there are not many Benidorm holidaymakers wondering what is it all about.
It has seldom taken from me more than 5 minutes the clear the regular screening and when there is rush hour, the priority line accepts also OW sapphires and emeralds.
A weak point is you never know when the screeners go on strike. It happens for various reasons every once in a while.
