Private buffer performance counters
Instead of being created by an SSIS instance, private buffers are created by particular transformation process themselves. Their purpose is to support and optimize the performance of temporary tasks in Pipeline, like the Aggregation transformation, Sort transformation etc.
Private buffer memory: this performance counter shows the full amount of physical or virtual memory used by all of the current private buffers within the Data Flow engine task in the monitoring cycle. During a data transformation, if the Data flow engine creates a buffer to support itself (not the transformation), that buffer is not considered as private.
