A StandardSetController or a SOQL LIMIT clause can be used to limit the number of records displayed at a time in a Visualforce page, and improve the performance and user experience of the page. A StandardSetController is a class that allows the developer to create list controllers, which can display a set of records using pagination, filtering, sorting, and other features. A SOQL LIMIT clause is a keyword that can be used to specify the maximum number of records to return from a query. By using either of these methods, the developer can reduce the amount of data that is transferred and processed by the page, and avoid the view state error, which occurs when the size of the view state exceeds the limit of 135 KB.
