Answer :  Close forms containing unbound OLE Objects if not in use. When unbound OLE objects activated, the memory used in that operation is not released until the form is closed. Also, form's load time is reduced when its code is moved to a standard module from the form module. The form's module doesn't always need to be loaded whenever form loads. However, the standard module has to be loaded at some point, but it stays memorized once it is loaded until you close the database.
