Which sense does this make? Is it recommended to have more than one instance on each (physical) machine? Increases this the availability of my cluster? Or should I have just one instance per machine?
It's occasionally a good idea to split one big instance into 2 to
avoid outages when the JVM pauses for garbage collection. I guess that
depends on how much memory you're using (the more heap, the longer a
full GC takes) and whether you need high availability.
