Design parameterized remote views to retrieve only the records your end-user will need to work with. The updating process will only send back to the server those new or modified data and deleted record information. So if you retrieve 10 records and the user only modifies 1, the information from just the 1 record will be sent back to the server for updating.

Your design will not have much affect on sending information to the server, but it sure will be a major factor on what is retrieved from the server.
