Hi Harry, This begs the question - how many D nodes do you have? How many documents? How large is the database? How many reads and writes?

Is it better for system performance to run with fewer beefy nodes or more not-so-beefy nodes? For example, would it be better to have: - two E Nodes built on 24 cores and 78 GB of RAM or - five E nodes with 8 cores and 16 GB of RAM Any insight or examples is appreciated. We have some internal info from other projects that give us some direction, but I am interested to know what others are doing and how MarkLogic is engineered for clustering. Is there a performance hit for more nodes? Does it really matter? Is it more a question of how much load there is to balance and hardware budget than system performance considerations?
