In my SSIS package I have a Lookup process that determines, if a particular ID is in an existing table. If an ID is present an update statement will be executed. If an ID is not present an Insert statement will be executed. Both of the operation are using the same table name. When I execute my SSIS package I get the following wait type under Activity Monitor:
- LCKM_IU
- ASYNC_NETWORK_IO
Does anyone know how to resolve this problem?
PS. My SSIS package is not using any linked server. Thanks.

Where are your databases stored? On same drives as local machine or on a SAN?

Thanks for the response, Peso. It is stored on a SAN. Please advice.

It probably means you SAN is not fast enough.
