Sam,
We run batch jobs every month for our clients, so what was done was we took note of how long some of these jobs ran. Compared it with the same jobs after the addition of the 2nd core and saw no change. I know, not the best comparison. That's why I was suggesting running some kind of system metric beforehand. First to have something say, "Yeah, you could see a benefit from another core." Second, as you're saying, you'll have something to compare to.
I don't recall the exact impetus for getting the extra core. It was ordered along with extra disk space (which was really needed).

Subject: Re: Cost of Activating Second Processor
Kurt,
Do you have any metrics from before activating the second processor that you will compare against?
If we get to test a second processor I'd want to have something better than "it feels faster" or "doesn't seem to have made any difference". I suppose maybe the elapsed time for our month-end process might be a good benchmark, but if you have an approach that you can share...
It's not that we have a sluggish machine--compiles are still satisfyingly fast, but some of our .NET apps that connect to the iSeries seem to be taking longer to get going, and the boss sees that. Of course, the network guys have virtualized all the Windows servers and that might be something to do with it. But it is seems very difficult to do any measurement on a mixed environment.

Hi Sam,
I don't have any answers for you, but we recently activated a second processor and so far we haven't noticed any impact. I wasn't a part of the decision to get the additional processor, but there must be a way to get some metrics on your system to see if a second processor would provide an ROI. Make sure you're up-to-date on PTFs. We're working on the PTF thing (just about there) and the next step is that there are some reports that can be ran that cost a couple hundred bucks (so I hear).
