Setting the number of archetypes in cache

The list of archetypes is kept in the cache for a specified number of uses before it is reloaded. To change the number of users, set <eng_instance_name>.db.engine.tune.max_archetype_list_use . The default is 100000.

For example:
movie_pref.db.engine.tune.max_archetype_list_use = 150000
