The queue helds a message index (a pointer) per message in memory. This index contains some fields for ordering and a 2nd pointer to the store. The actual message is in the JDBC store. You cannot avoid it. With such an amount of messages you would need to increase the heap size.
The reason why it takes so long at startup with that amount of messages is that the queue builds up the message indexes from the JDBC store. Take a look at the SQL statements of the JDBC Swiftlet. They are configurable. You might also add an index on the resp. database columns.See here
