how much memory overhead per node?

[nnnnn]

Has anybody done some analysis or profiling to determine what the memory overhead for TreeCache is per node?

[genman]

It's actually fairly high... 145 bytes per Node, plus the size of the FQN. That's for 2.0, 1.3 should be about the same.

A couple of changes here and there, like using new HashMap(0) etc. for the node data reduces it to 81.
