Don't create a seperate lam user for each user, but DO create
more than one. If one account suffices when no failures occur,
and if failures costs you 50% of your duty cycle, have two users,
and so forth, using them in round-robin fashion. That's what we
do, and we achieve job rates of > 2000 jobs per hour over weeks
of running.
