Think about mysql with innodb. One central variable is buffer_cache which should be "as much as possible". When only one instance is running on a server you can make a feasible guess, e.g. 80% of physical mem. As soon as two instances are running on on server each instance can only have 80% / 2 of memory for buffer_cache. As soon as you "overbook" real memory things go dramatically worse. Any ideas?
