Good bandwidth and reduce the amount of data transferred.
In particular remove unnecessary updates - only update if the value is changed, don't insert then update, do multiple updates on a single row in a single statement, don't update a whole large table - or if you do see if you can transfer it by snapshot rather than transactions.

Cursors are useful if you don't know sql.
SSIS can be used in a similar way.
