An interesting question.  Ordinarily I would not recommend trying to submit
many jobs at all - I would write a server program to listen to a data queue
and have program A send entries to the data queue.  As the workload
increases, you can run multiple servers all listening to the same data
queue.  There have been posts in the past about this topic;
http://archive.midrange.com/midrange-l/200006/msg00232.html is a good one.

The point being that starting a brand new job is expensive; sending a
parameter to an already running job is much cheaper.  If you aren't able to
change the architecture, investigate prestart jobs.  Anything you can do to
minimise the cost of the new jobs is a step in the right direction.
