if this has been happening for some time, some tables
might possibly have become bloated with dead rows, so
a one-time VACUUM FULL or CLUSTER on these might be indicated
to speed up reaching the steady state.

I think the max_fsm_pages is a minimum recommendation, so you
might want to look at VACUUM VERBOSE output after setting it,
to see if an even higher value is indicated

if you have got a lot of memory, you might want to experiment
with these a little
