GeistGeld has been humming along on 15 second blocks for what, years now?
So far the biggest problem was been the huge amount of RAM needed, more even than I0Coin.
I guess in a couple of years we will find out whether the RAM usage is due to the sheer number of blocks.
Or, we could update GeistGeld's code in case maybe it has a memory leak, as I0Coin is thought to have.
