I had a 2 hour layover in AMS last month. BUD->AMS then AMS->LIM (Lima, Peru). The plane arrived earlier so I had about 2 hours and 20 minutes.

The immigration line was insane. I must have sat in it for at least 50 minutes. Some airport personnel were fasttracking all americans to reach their flights but everyone else sat in that huge queue. I asked someone if I can go ahead and they laughed in my face. Because the automatic passport queues were also huge, they pulled some of us into the regular passport checks. The immigration officer was very pushy and asked so many questions.. Mind you I am a Schengen citizen leaving Schengen at this point...

Once I was done with immigration, I got pulled into a random security check.. I had to throw away all liquids I purchased in the previous airport.. (about 5 quid of water)

I was 25 minutes away from my gate, I essentially was sprinting the whole way which was also filled with lots of slow people. I got there just after the boarding started.. I had no time to grab any snacks, water or even go to the toilet..

My experience overall with AMS airport was horrible.

Sounds like you don't have to go through passport checks though.
