PSB registration does not take two minutes, literally or figuratively. I was at the 出入境 for about an hour two weeks ago. This one visit was one of many visits. Yesterday, I went to register at the local 派出所. I was the only person there. They processed all my documents (three passports) in one hour.
I should amend my statement above: PSB registration does not take two minutes for me. You are fortunate that it only takes two minutes for you (I am assuming you mean figuratively, though if you are being literal I am even more envious).
China is a big country. There are places in China where the administration is very efficient and effective. Most places are not. I say this from personal experience and from the experience of others who don't live in large, developed cities. Some generalizations are accurate, but like any generalization, the veracity may vary from your own local experience.
At a hotel where they are supposed to register for you it might take 2 minutes. But in my experience it takes anywhere from half a day to a week in smaller city. Half a day is the minimum because you get directed from one place to another and wait in lines. A week is how long it could take of you're missing anything they require such as a photo. Yes, it varies widely.
