I'd argue against this because it's at once too little control and too much
control. The Workload Manager allocates total processing resources to
different workloads, regardless of the number of processors. You can
achieve the same effect by telling the Workload Manager to allocate 1/4th
of the available CPU time on a 4-processor system to a given workload. But
whether that ends up being one processor all the time or all four
processors 1/4th of the time shouldn't make any difference. There's no
point in having a processor idle just because there's no work at any given
instant for its workgroup.
 
The only possible advantage to this would be to increase cache locality,
and it's doubtful whether the resulting performance improvement would be
measurable in a typical application.
