When the SSIS execution engine runs out of physical RAM, it relies on a failsafe known as "buffer spooling." The engine creates temporary files on physical hard drives to swap out memory pages. Because disk I/O speeds are drastically slower than RAM, buffer spooling will destroy package performance.

Summary

The architectural components you choose for your pipeline heavily dictate its resource footprints. Selecting non-blocking alternatives ensures continuous data streams without unnecessary infrastructure delays. Component Class Impact on Processing Recommendation Derived Column, Multicast Processes data instantly row-by-row without stopping. Use as much as possible for transformations. Semi-Synchronous Merge, Lookup Pauses streams briefly to fetch or align related rows. Optimize cache sizes to keep latency low. Asynchronous (Fully Blocking) Sort, Aggregate Halts the entire pipeline until the last row is read.
