By default, the UPDATE statement generated by the View Designer uses "Key and modified fields" so that you could get a SQL UPDATE statement that includes the memo field in the WHERE clause. This will greatly slow down the statement.

On the Update Criteria tab of the View Designer, you may want to change the SQL WHERE statement to Key fields only.
