You can improve Replication Agent performance on a machine with multiple processors by adjusting the size of the LTI queue.
The lti_max_buffer_size parameter has been updated to specify the maximum number of items that can be stored in the LTI queue. Set this parameter according to the number of LTL formatter process threads and the number of processors available.
The lti_max_buffer_size specifies the maximum number of items that the log reader can place in the LTI queue.
Setting lti_max_buffer_size to a value that is too large may degrade performance if there is insufficient memory available.
