There have been manyoccasionswhere I've needed to run multiple copies of the same process for performance reasons. Let's say for example that a stored procedure can process 10 records/sec, but I have 1,000,000 records to process. It would take 27.7 hours to process at the previous rate. If I could break up this process into discrete pieces I could run multiple copies and reduce the total run time in a linear fashion (that is if it takes 10 hours to run 1 copy, it would take 5 hours to run 2 copies...1 hour to run 10 copies). There is a computer operation known as, Modulo.
