Actually, the biggest single difference in time/convenience IMHO was that there was a single security checkpoint for all flights in SFO in contrast with Schiphol where the security checkpoint was just prior to boarding the plane. The guys checking my papers, the guy in Schiphol was more thorough, slightly less friendly than the one in SFO. The security guys when going through the scanners were definitely more friendly in Schiphol than SFO.
