In an ideal world yes, it would be great to just turn up and sail through security within minutes at what is one of the peaks in flights, but, we don't live in an ideal world. But, when you have up to 13 flights going off at roughly the same time, apart from staggering people through check in (EI giving each flight an allotted time through security), I don't see what else you can do.
Like I say, around 30 mins is the norm at a fair few airports now.
