Rahul It's not because of the Order Scheduling module, it's because you have stores that have enabled Dynamic Open/Close time setup.
The cache is cleared every minute to make sure the open/close actions are reflected throughout the website.
If we do not clear cache, and if a store is automatically turned OFF (According to their close time) then on the customer application, it will still show the store as ACTIVE.
In regards to whether or not you will be benefited from the SuperCache module:
Depends on how you consider things. If you expect many active users on your website, then YES, you will be benefited from SuperCache even if clears the cache every minute.
Because even if the cache is cleared every minute, in the next request it is again cached and all subsequent requests are served from the cache, not the DB. After a minute it is cleared again and cached again at the same time if a user visits the homepage/item page.
Hope that makes sense?
