We have the same kind of application here.
We vacuum according the load, if the load start to be "high"
we vacuum ->earlier<-, ok there is a little penalty on users, but as soon
the data-base is clean, the performance is dramaticaly improving
and the load just drop. So instead to have user penalised
for a long time, we just use it as a trigger to clean the base.
(we do not want the user to vacuum at will)
