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 Microsoft SQL Server 2000 Service Pack 4.

MORE INFORMATION

After you apply this hotfix, you can set the incoming Tabular Data Stream (TDS) network affinity for an instance of SQL Server by using the startup parameter -N##. This parameter is case-sensitive.

SQL Server uses a high-priority thread to handle incoming TDS I/O completion activities. The high-priority network thread can be affinitized to a processor by providing the -N## startup parameter. The mask that is passed to the -N## parameter is used in a SetThreadAffinityMask call to establish the network thread's affinity.

By default, the network affinity is not set. However, if you must establish network affinity for the computer running SQL Server, Microsoft recommends that you set the mask to the last physical processor. When you set the affinity mask to the last physical processor of your computer, all incoming connection activity is automatically affinitized with the last physical processor, and the UMS scheduler that is associated with the last processor is correctly weighted to allow more network-based activities.

For high-end systems, you can combine the -N## startup parameter, the -I## command-line parameter, the sp_configure stored procedure affinity mask, and the Virtual Interface Architecture (VIA) card affinity settings to manage SQL Server resources.
