We recommend that you consider applying these updates to improve the performance of SQL Server instances. The degree of improvement will depend on various factors, including workload pattern, contention points, processor layout number of processor groups, sockets, NUMA nodes, and cores in a NUMA node , and the amount of available memory in the system.
The SQL Server support team has used these updates and configuration changes to achieve reasonable performance gains for customer workloads that use hardware systems that included several NUMA nodes and lots of processors.
