Default Full vacuum really slowing query down

I have a query that takes 2.5 sec if I run it from a freshly restored
dump. If I run a full vacuum on the database it then takes 30 seconds.

Would someone please comment as to why I would see over a 10x slow down
by only vacuuming the DB?

I am using 8.3.1
