SSIS import, flat file vs straight ODBC

-

i running performance test data import into sql server 2005 database teradata source database.

case1: data downloaded from teradata flat file using odbc driver , loaded sql database using bulk insert.

case2: data downloaded from teradata using odbc driver sql database through data conversion.

download times in case 2 on average twice of in case 1 after 10 runs. can me understand why case though case 1 has data hop in flat file?

thanks,
vikram

to improve results, you're going have more drastic on database end.  you're not going ssis load faster bulk load without database-end tweaks.  read sqlcat site ideas on partitioning, indexes, etc...  you're going have identify bottleneck - memory, i/o, cpu, ... address it.
