SYMPTOMS

When you put ADO recordsets into the body of an e-mail message, the amount of time required to serialize the recordset increases significantly as the size of the recordset increases. For instance, by doubling the size of the recordset, the time required to serialize the recordset may triple, depending on the amount of data that is being serialized.

CAUSE

Memory allocation and expansion is not optimized to allow for efficient memory expansion.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

Enhanced memory allocation and expansion techniques are implemented in the Message Queuing code that brings the serialization time into a more linear relationship with the size of the recordset.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows 2000 Service Pack 1. Microsoft has confirmed that this is a problem in Microsoft Message Queuing 2.0.
