What is the difference between the table buffer and the user buffer?
The table buffers are in the shared memory. Buffering the tables increases performance when accessing the data records contained in the table. Table buffers and table entries are ignored during startup. A user buffer is a buffer from which the data of a user master record is loaded when the user logs on. The user buffer has different setting options with regard to the ‘auth/new_buffering’ parameter. For more information, see note 209899.
