Manila - Philippine Airlines International terminal takes the prize for me.

- Car gets checked to get into the airport (well, they look in the trunk)
- Line up and show your booking/ticket and passport to the man with the gun to get through the building doors
- Security check number 1 - full screen of bags and body, including pat-down
- line up for check-in (after finding which desk to use)
- line up to pay for Aiport Tax
- line up for immigration control in a little corner of the terminal, then when stamped, turn back from where you came and go through to
- final immigration control and security number 2

While I have been through some US airports and it has taken a long time to be processed (Orlando comes to mind), Manila is ... well.... different.
