write updated data from a Value List Handler to the db

I am using the Value List Handler Pattern to read a large set of data. My DAO returns a HashTable containing VOs. The data is displayed as a HTML from and can be edited -> so I need to write the changed data back to the database (in bad cases the whole HashTable). Any suggestions how to do this with good performance?

Thanks in advance.
