Details

Choosing the optimum value for the READBUFF= option requires a detailed knowledge of the data that is returned from the information map and of the environment in which the SAS session runs. Buffering data reads can decrease network activities and increase performance. However, higher values for the READBUFF= option use more memory. In addition, setting a high value for the READBUFF= option could yield stale data if the data source is updated frequently.
