There are so many different possible setups and Java has comparingly bad
support for measuring the size of an object. I suggest that you use a
profiler for your particular setup and measure resource consumption.
We'd appreciate if you post your measures here.
There's an article about CDO tweaks, be sure to read at least the
section about caching: http://wiki.eclipse.org/Tweaking_CDO_Performance
Generally we try to find designs with the best tradeoff between
functionality and resource consumption, but if you find optimization
potential report it here ;-)

If, by repository, you mean the backend, then no.

Minimally. But sessions are expected to load revisions, hence their
number might impact the overall consumption.
