Slow insertion in Amazon Redshift

I'm testing the BO Data Services as ETL tool for data extraction having as Amazon Redshift destination. However, the performance for the inserts into Redshift is very bad.

On average, the Data Services inserts about 5 records per second. (I made tests with Talend and it already entered 22000 reg / sec)

We have a BODS running on the Linux platform x64.

For connection, we use an ODBC connection created and configured as Amazon recommendations.

Does anyone have any idea how I can provide more performance in data inserts in Redshift using bods?

Thanks
