Hi Francesco

most probabely this is due to the auto vacuum option on and if auto vacuum
is on then the in condition of high transaction on database it slows the
speed of the hole database.Set it off in postgres.conf and vacuum and
reindex transactional tables manualy with in  every two million
transactions.
like
vacuum full <table name>;
reindex table <table name>;
