Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.This problem was first corrected in Microsoft SQL Server 2000 Service Pack 4.
With this fix, you can set the incoming Tabular Data Stream (TDS) network affinity for an instance of SQL Server by using the -N## (case sensitive) startup parameter.
SQL Server uses a high priority thread to handle incoming TDS I/O completion activities. The network thread can be affinitized to a processor by providing the –N## startup parameter. The mask passed to the –N## startup parameter is used in a SetThreadAffinityMask call to establish the network threads affinity.
By default, the network affinity is not set. However, if you must establish network affinity for the server that is 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 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 with the –I## command line parameter, the sp_configure stored procedure "‘affinity mask", and the Virtual Interface Architecture (VIA) card affinity settings to manage the SQL Server resources.
