Well, the real cost is qmail-queue which is invoked by qmail-inject.
qmail-queue is syncing each submission so that it can gaurantee that the
mail will not be lost. Doing lots of syncs to the queue is an expensive
disk i/o operation.
Your solution is to put your queue on a disk subsystem that can sync
at the rate you want to submit (and deliver). Some do this with a faster
disk, some do this with a partition that is spread across multiple
spindles. How you do this depends on your OS type and what sort
of hardware you are willing to throw at it.
