doesn't look like a trivial issue,
probably the db won't grow bigger than a GB in couple of years,
although the usage of the writes is relatively 1/10 compared with the
writes,
every actions gets logged, what makes the writes heavy as well,
I just got what seems to be a good mysql book with lots of performance
