Virtual processors......they are fun to play with, aren't they.

As everyone's environment is different, I would have a look at this redbook:
http://www.redbooks.ibm.com/abstracts/sg248000.html?Open

Page 15 (1.3.7) starts talking about virtual processors.

a rule-of-thumb is to have the same number of virtual processors as there are physical processors assigned to the partition, round up if you have partial processors assigned.

A while back two servers were migrated to an LPAR'd 570. I am not seeing the performance gains that I expected so I started looking at how the LPAR's are configured. The LPAR's are setup to be uncapped with the same number of processors and virtual processors. For example, one of the LPAR's has 6 processors. If I understand it correctly, I could have up to 60 virtual processors? In practice, what should the number of virtual processors be set for that partition? What factors do I need to consider, when trying to decide?

Thanks.
