DAC task with Informatica mapping and stored procedure (very slow)

Question

Hello,
We have a DAC task that launch an Informatica Workflow with a simple query and stored procedure, like this:
SQL QUERY
==========================
SELECT
W_ACTIVITY_F.ROW_WID,
W_AGREE_D.AGREE_NUM,
W_PRODUCT_D.ATTRIB_51,
W_SRVREQ_D.ATTRIB_05,
W_ORG_DH.TOP_LVL_NAME,
W_ORG_D.ATTRIB_06,
W_PRODUCT_GROUPS_D.PRODUCT_LINE,
W_PRODUCT_D.PROD_NAME
FROM
W_AGREE_D,
W_SRVREQ_F,
W_ACTIVITY_F,
W_PRODUCT_D LEFT OUTER JOIN W_PRODUCT_GROUPS_D ON W_PRODUCT_D.PR_PROD_LN = W_PRODUCT_GROUPS_D.PRODUCT_LINE,
W_ORG_D,
W_SRVREQ_D,
W_ORG_DH
WHERE
W_SRVREQ_F.AGREEMENT_WID = W_AGREE_D.ROW_WID AND
W_SRVREQ_F.SR_WID = W_ACTIVITY_F.SR_WID AND
W_SRVREQ_F.PROD_WID = W_PRODUCT_D.ROW_WID AND
W_SRVREQ_F.ACCNT_WID = W_ORG_D.ROW_WID AND
W_SRVREQ_F.SR_WID = W_SRVREQ_D.ROW_WID AND
W_ORG_D.ROW_WID = W_ORG_DH.ROW_WID
STORED PROCEDURE
===========================
ConvSubProy(W_AGREE_D.AGREE_NUM,
W_PRODUCT_D.ATTRIB_51,
W_SRVREQ_D.ATTRIB_05,
W_ORG_DH.TOP_LVL_NAME,
W_ORG_D.ATTRIB_06,
W_PRODUCT_GROUPS_D.PRODUCT_LINE,
W_PRODUCT_D.PROD_NAME)
The mapping is very simple:
Source Qualifier -> Stored procedure -> Update strategy (only two ports: ROW_WID and custom column) -> Target Table
When I launch the DAC Execution Plan the corresponding task take much time (40 minuts). But when I launch the corresponding Workflow from Informatica PowerCenter Workflow Manager this only take 50 seconds... when I see the log session for the task I can see that much time is spent on the time of the updates. For example, when DAC is running the writer updates 10000 records every 6/7 minuts, but when Workflow Manager is running thw writer updates 10000 records every 8/9 seconds.
So, what happens (in the DAC) to that so much time difference? Is there a way to reduce the execution time when the task is launched from DAC?
Thanks

Have you tried using bulk load type?
In Workflow Manager can you open the associated task, navigate to the mapping tab and seled the target table.
What is the value for "Target load type" and which of the following boxes are checked: Insert, Update as Update, Update as Insert, Update else Insert, Delete?
