I have inserted 500 thousand records and the DCD is 24mb. When I do a mnesia:stop() and start() it takes over 10min just to load the test data. I originally had planned to have this fragmented and have at least 200mb per fragment but at 10min load for 25mb the whole idea seems impossible now as it would take over 2hours to start a node. I find it hard to believe this is by design? Can anyone tell me what I am doing wrong?
