Stephane -
The slowness --- at least as I observe at my end, has not been
fixed.
In the caase of vc-backends, I'm able to avoid global crawls
across NFS filesystems by setting
;;; vc speed up:
(setq vc-ignore-dir-regexp
"\\`\\([\\/][\\/]\\|/net/\\|/home/\\|/afs/\\)\\'")
Notice the addition of /home above -- in my case /home is nfs
mounted.
I strongly urge you to reconsider forcing all users to take the
hit of searching for project settings.
For now, I've defadviced hack-dir-local-variables like so:
(defadvice hack-dir-local-variables (around fix-slowness pre act comp)
"Restore democracy, restore speed"
nil)

Best Regards,
