Use these configuration parameters together to increase the number of transactions that can be grouped as a single transaction for application to the replicate database.
If the average number of commands per transaction is small (five or fewer), you can use dsi_xact_group_size and dsi_max_xact_in_group to improve transaction application time.
Sybase recommends that you set dsi_xact_group_size to the maximum value, and use dsi_max_xact_in_group to control transaction group size.
