Re: Cost of Activating Second Processor

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
