I think it's a function of the airport itself. I have been to Qatar and the security was as simple as sliding my bag in. I didn't have to remove my belt, watch, or phone.
Total time to pass security: 2 minutes.
Total time to pass immigration: 15 minutes. (depends on traffic).
I remember a friend who caught her flight just 10 minutes before gates closed. She made it.
Edit: HaHa. Forgot my local airport. I can get from the entry door, to the Airplane bus in 2 minutes (security + immigration + walking). It usually only have 1 or 2 flights per day and feels very friendly.
