It takes a long time to compile my UE5 project

Firstly, thank you !

  1. My project is still in the initial stage. I just created 18 classes. Some of those has no merber function.
  2. I did not specific timing the average compile time, but I remember the longest compilation tooks at least 15 minutes, but the fastest took a few second. I am wondering about why adding a line of code ,which is used to assignment , takes a long time to compile ?

belowis my PC’s hardware list:

CPU: AMD 5800x

SSD 1T (storage software, including UE, VS)
