> Deserializing the Package objects from storage to memory consumes large amount of memory.  My tests showed that for a serialized size of 1MB, 18MB of memory would be consumed during deserialization, mostly from the method org.drools.rule.Package.readExternal.  A test program with resulting profile data would be uploaded.
