We have a package where it copies about 100 million records each day from the OLTP to the OLAP enviornment.We are using OLDEDB Destination with fast load to do this.It works ok till 40 million and after that it slows down drastically and almost stalled at somepoint.
Is there anything that Im missing.
?
Currently I have row commit size to infinite and row per batch size to 1 million.
Thanks

Reduce both to 10000.  Also, please post the INSERT and SELECT queries so that we can help further.  Finally make sure your tempdb is well sized and that you do not have too frequent extent.  hope this helps...

How long and when is the insert running? Common problem could be:
1. Any other processes running on source/destination box at the same time? Backup perhaps?
2. Doeas destination DB have enough free space? Could be that after first 40 mil. rows, DB space increasing causes additional IO.
3. Network load is fine?
