@sickcodes commented on GitHub (Nov 14, 2021):

Test these I have had this experience before:

(as root)

To Clear PageCache, dentries and inodes:

$ sync; echo 3 > /proc/sys/vm/drop_caches

To Clear PageCache only:

$ sync; echo 1 > /proc/sys/vm/drop_caches

To Clear dentries and inodes:

$ sync; echo 2 > /proc/sys/vm/drop_caches
