Increasing DTM buffer size

The DTM buffer size setting specifies the amount of memory that

Data Integration

uses as DTM buffer memory. When you increase the DTM buffer memory,

Data Integration

creates more buffer blocks, which improves performance during momentary slowdowns.

Increasing DTM buffer memory allocation generally causes performance to improve initially and then level off. If you don't see a significant increase in performance, DTM buffer memory allocation isn't a factor in mapping performance.

To increase the DTM buffer size, open the task and edit the

DTM Buffer Size

advanced session property. Increase the DTM buffer size by multiples of the buffer block size.
