Pipeline Performance Improvements in SSIS ( SQL Server Integration Services ) 2008
In SQL Server 2008 SSIS, the data flow task has been redesigned to do dynamic scheduling and can now execute multiple components in parallel, even if they belong to the same execution tree. In other words, several threads can work together to do the work that a single thread is forced to do by itself in SQL Server 2005 SSIS. This can give you several-fold speedup in ETL performance.
