[ndnSIM] Memory Usage in ndnSIM and NFD

Hi,
I have a question regarding the memory usage in ndnSIM2.0 as I run in to
memory troubles with my simulations. Currently I simulate networks with
the size of 100-200 nodes per simulation. Using ndnSIM1.0 this was no
problem as the payload of Data Packets could be set to "virtual", so
just an integer coded the size of the payload. Due the fact that much
more memory is required in ndnSIM2.0 and through the connection to the
NFD, I assume that the payload is now really stored in the memory? Is
this assumption correct? If so, I think this leads to problems
simulating larger networks even on very powerful hardware.
Could someone explain in detail what "parts" of the Interest/Data
packets are really physically stored in memory? How do the new/old
Content Store(s) store Data Packets? Is a copy of each packet stored in
each Content Store, or is a single copy shared among several Content Stores?
Best regards,
Daniel
