compilation of ccache (modify several configurations, make-J4): 23 minutes 48 seconds It seems that the configuration is modified (I changed the CPU type ...) the impact on ccache is great, because after the basic header file changes, All cached data will be invalid and must be re-entered. However, if you only modify the code of some. c files, the ccache effect is quite obvious. The use of ccache is not particularly dependent on the project, and the
