Remove Old Queries
Your AF Ultimate site uses a cache folder to store mysql queries in. This means several people can reuse 1 database query (such as loading the newest articles list) allowing the database to not be used again for that query until the cache files are expired or deleted by you.
You can set the expired time in your admin setting's page, but if you wish to clear it manually, then it won't hurt anything to do so.
Simply click on the Admin Actions\Leave Today's Cache link, and the frontend cache will be emptied of everything except the queries create on that day!
You will see the file names being deleted, and a message at the end when it's done.
