Reducing Paging

Reducing Paging

Paging occurs when the Integration Service process operating system runs out of memory for a particular operation and uses the local disk for memory. You can free up more memory or increase physical memory to reduce paging and the slow performance that results from paging. Monitor paging activity using system tools.
You might want to increase system memory in the following circumstances:
  • You run a session that uses large cached lookups.
  • You run a session with many partitions.
If you cannot free up memory, you might want to add memory to the system.
