The runtime seems to be dependent on what hind of activity you do. If you
frequently rollback inserts, vacuum seems to take longer. Say, a database
with 1m records which endures 5m inserts + rollback is going to take a
while to vacuum.
Just my informal observations, not based on structured testing.
