Why Codeforces rating update takes a long time?
I noticed that some contest's rating updates very quickly, on the other hand, others take a long time. What's the reason behind it?

Even I am waiting for the same :/
I need to know the reason.
Ratings after Div 2 and Div 1 contests are updated within 3 to 4 hours since there is no hacking period after the contest. Hacking occurs before the contest ends.
As for Educational rounds, Div 3 and Div 4, there is a 12 hours hacking period immediately after the contest ends. And then, after 3 to 4 hours, the rating gets updated.
As for today, the matter is different from general Div 3 rounds. The question D in yesterday's contest had some problems. You can check the problem here:
