Re: Cost of Activating Second Processor

[Tommy.Holden@xxxxxxxxxxxxxxxxxxxxx]

Are you really CPU bound or is it I/O or memory that's the issue.  First 
thing before I jumped in would be to determine where your bottleneck is. 
Also if you are using a lot of SQL I would run index advisor for 
statements executed over your largest tables to ensure that proper indexes 
are built.  If not then the system will spend extra CPU & memory to create 
temporary access paths, etc.  there's just too many variables to consider 
that can affect performance.  I know I didn't answer your question but 
that's just some food for thought.  You might not need more CPU just more 
performance tuning of your apps, etc. (which would seem to be far less 
$$$)

We have a Power 6, M25.  P10 Group.  V7R1.  One processor is activated.

Asked the Business Partner the cost of activating the second processor 
and they said:

"Cost for the 2nd processor and OS License would be $17K but also makes 
your SWMA charge double."

Does that sound reasonable?  (We need to license OS/400 again for the 
2nd processor?  SWMA doubles because we'd be in a new group?)

I'm not sure a second processor will have much impact.  Most of our 
activity is RPG & SQL based with some .NET access, and day end is nearly 
all single threaded.

Can we turn the second processor on for free for a week or a month to 
see the impact?

Thanks,

Sam
