Best Practice for processor sets

Hi,

Is there any Best Practice on how to create processor sets on T and M- series?

For instance, if I have a T5-4 (4 x 16 cores) and need to have a processor set with 16 cores for a solaris zone.

Alternative configurations:

1 - Allocate one of the 4 cpu boards to this pset (1 x 16 cores, VCPU 0-127)

2 - Allocate 1 core from each cpu board (4 x 4 cores, VCPU 0-32 + 128-159 +  256-288 + 384-416)

Can I expect the same performance for these alternatives?  (context switches, cache line etc.)

/Best Regards

Ulf
