Dan's theory says in case of 6 nodes,
there's relatively more 3-way traffic, which could slow down the overall
performance. Correct, Dan?
From: Dan Norris <dannorris@xxxxxxxxxxxxx>
... In any case where a
block is cached in another instance, there are three parties involved: the
requestor, the holder, and the global resource master for the requested
block. In a two-node cluster, two of these three parties are the same
instance and therefore the messaging between them is very fast. When a third
node is added, there's a statistical probability that these three parties
will involve all three instances for a significant portion of the
occurrencesof this situation. In the case where three instances are
involved,the communications take longer since all messaging has to cross the
interconnect.
