How did you determine it wasn't enough? As others have stated, you're
causing your own slowdown by running vacuum so much on tables that aren't
changing.
If you have a particular table that needs more frequent vacuums, like a
session table or something, maybe just cron that. But autovacuum should be
doing it more often than an hour anyway in that case ...
