Running SSIS packages in separate memory allocations or increasing the default buffer size?

How much memory is allocated to SQL Server? How much memory is allocated outside of the SQL Server process space?

The reason I ask is becuase SSIS memory is allocated from the memToLeave area of memory that sits outside of the SQL Server process space.

See here for details on configuring the amount of memory available to the memToLeave portion of memory.

For generic performance tuning of SSIS consult the following article.

I hope this makes sense but feel free to drop me a line once you have digested the material.

Cheers,
