Two notes:

1. The share assigned to a partition is divided by the number of 
processors of the partition.  This is the weight the LPAR dispatcher uses 
when it searches for a "virtual" processor to dispatch on a real one.
Example: 2 parttions, each has weight 40, partion 1 has 1 engine, part 2 
has two.  So, the LPAR dispatcher has 3 virtual processor to run:
 Part 1 CPU 1 weigth  40
 Part 2 CPU 1 weigth  20
 Part 2 CPU 2 weigth  20 
So, when the system is really busy, the LPAR dispatcher will tend to pick 
the processor of part 1 more than those of part 2.  And thus indeed: 
adding a logical processor to a partition may degrade its performance. You 
will need to increase the weight of te partition.

The VM's dispatcher works the same way.

2. INDICATE 100% means VM never placed itself in voluntary wait.  It 
doesn't tell *anything* about how cpu was actually used.  Is IND wrong? It 
depends:
 - for an end-user IND is right: the system is fully loaded
 - for a capacity planner, IND is false.
