SMS 2003 Advanced Client takes lots of time to download many policies

Symptoms:

Microsoft Systems Management Server (SMS) 2003 Advanced Client takes lots of time to download many policies.

Cause:

This issue occurs because Background Intelligent Transfer Service (BITS) cannot handle more than about 500 simultaneous jobs. When more than 500 simultaneous jobs are submitted, many I/O operations must occur, and many BITS state files must be maintained. Therefore, a decrease in performance occurs.
