You didn't attach cygcheck output, so some of my reply is just a guess.
Is /mnt your preferred spelling for the cygdrive prefix?  Is /mnt/g a
local or remote disk?

              ^^^

This might be why - to correctly fill out the n_link member of struct stat
for a directory on a local drive, cygwin counts how many subdirectories
live in that directory.  Depending on how your disk is filled, it may take
some time to effectively readdir the directory to get that count.
Extra-full directories take longer to traverse, even if the traversal is
only to calculate how many subdirectories were encountered.
