I  've got a new Laptop (with Fedora 21), also with Emacs 24.5.
I indeed have seen some slowish behavior inside ESS... I think in the
context of argument matching of functions  also  emacs dired is
extremely slow if used for a directory with 1000's of entries...   but
definitely did not see bad startup behavior of emacs ..
