Stats traffic should not be affected at all. It just user the same messages already there to increase a couple of
globalcounters per database. The only thing
that increases is that the stats file gets another 5 counters per database. Given how few databases you normally have
comparedto number of tables, I would
think that should be pretty trivial.
Scanning them on demand will require loading the whole stats file into the backend instead of just the current
database,which I considered more bloated..
