That depends on configuration settings and on whether the computer
(or VM) is so swamped that the autovacuum task is starved for cycles.
Also on any overrides of statistics targets for those tables.
Please show us the output from running this query:

Have you overridden any statistics targets?
A description of the environment would also be good. Hardware? Load?
