RE: Starting jobs to read from a data queue

["Shaw, David" <dshaw@xxxxxxxxxxx>]

Booth,

Other folks have mentioned running in batch.  However, you need to be
careful of how many of these jobs you have running, simply because if you
run more than your machine can efficiently handle, you'll actually slow it
down by having too many of them running.  I would be surprised if even the
biggest one-cpu machine would handle 14 average batch jobs simultaneously
without thrashing.  On the other hand, a 12 or 24-way system shouldn't have
any trouble at all with 14.  It would probably be worth your while to do
some experimenting on this to find your optimal number, unless you actually
do have a multi-cpu monster.
