Hi,
I'm not sure I understand your following comment: "The real indicator is that the slow nodes are at 98% all day. With performance being
limited by the slowest node it would seem reasonable that CPU utilization for the entire system would be 98%."
Given that you've got a co-existence environment then it seems (to me) to be perfectly reasonable that if the slower nodes are X% busy,
then the faster Nodes are typically going to be
I've seen this on at least one other customer system. The new Nodes were 'twiddling their thumbs' at around 50-60% busy whilst the old
Nodes were unning at 98-100% for many hours of the day. We recommended a re-config and now the Nodes are a lot better balanced.
Cheers,
Dave
