well, what i know about mnesia is that it's ets tables incase of ram copies tables and dets incase of disc copies tables.
What i could asure to you is that mnesia is much more slower than mnesia.
Note: Mnesia shouldn't be used in complex operations it's prefered to be used in easy operations that need fast processing in memory.

It sounds like there would be a similar slowdown effect with Mnesia + SMP too.
Is that correct?
Thanks,
