When you start a new session, does the command run as fast as in
"emacs -Q", or is it already significantly slower?  If the latter, it
might be better to bisect your .emacs until you find the part that
causes the slowdown.

I see nothing of interest in the profile.

Does this happen with renaming any file/directory, or only with files
on some specific filesystems?  Are those filesystems local ore remote
(NFS, Samba, etc.)?

If you try renaming a single file with "M-x rename-file RET", does it
also take 2 sec?
