[jboss-user] [JBoss Cache: Core Edition] - Memory overhead per node?

[dukehoops]

I am trying to ballpark expected heap consumption per FQN in JBC3 w/ MVCC. At high level, what is the incremental amount of heap consumed when an additional node is stored in cache?

Disregarding the size of cached object itself, AFAIK there are several addl objects created: Nodes, Node wrappers, etc.

What is the additional memory cost of reading a Node? AFAIK the node state is copied into InvocationContext (but also in TransactionalContext)? Any rules of thumb to help approximate?

thanks
