Server Properties (Processors Page)

Applies to: SQL Server

Use this page to view or modify your processor options. Processor affinity settings are only enabled when more than one processor is installed.

Options

Processor Affinity

Assigns processors to specific threads to eliminating processor reloads and reduce thread migration across processors. For more information, see affinity mask Server Configuration Option.

I/O Affinity

Binds Microsoft SQL Server disk I/Os to a specified subset of CPUs. For more information, see affinity Input-Output mask Server Configuration Option.

Automatically set processor affinity mask for all processors

Allows SQL Server to set the processor affinity.

Automatically set I/O affinity mask for all processors

Allows SQL Server to set the I/O affinity.

Maximum worker threads

0 allows SQL Server to dynamically set the number of worker threads. This setting is best for most systems. However, depending on your system configuration, setting this option to a specific value sometimes improves performance. For more information, see Configure the max worker threads Server Configuration Option.

Boost SQL Server priority

Specifies whether SQL Server should run at a higher Microsoft Windows scheduling priority rather than other processes on the same computer. For more information, see Configure the priority boost Server Configuration Option.

Note

This option is not available with SSMS 18.x and later versions.

Use Windows fibers (lightweight pooling)

Use Windows fibers instead of threads for the SQL Server service. This is only available in Windows 2003 Server Edition. For more information, see lightweight pooling Server Configuration Option.

Note

This option is not available with SSMS 18.x and later versions.
