Best way is to limit the number of "lmtp" clients in to something
around 2 if you have a single mailstore (single disk/array). because massive
parallel local deliver leed to locking problems and don´t speed things up.

See Postfix for notes on parallel deliver for local mail!!

Use transport map to deliver direkt to lmtp to get the advantage of single
instance store.
