It's cool isn't it. Anyway, the memory consumption
of mnesia is easily measured, just creat a bunch of tables, populate
them, use the info functions in mnesia to see.

The only situation where mnesia sucks from a memory consumption
perspective is the area of very large transactions.

That is a transaction that writes very large amounts of data, particularly
if the target tables are replicated. 

Apart from that, the memory requirement of mnesia are very low.
