SQLServer通过以下两个关联掩码选项来支持处理器关联:affinitymask(也称为CPUaffinitymask)和affinityI/Omask。对具有33到64个处理器的服务器的CPU和I/O关联支持要求分别使用affinity64mask服务器配置选项和affinity64I/Omask服务器配置选项(这2个服务器配置选项仅在64位操作系统上可用)。http://technet.microsoft.com...

on GitHub How to Set the CPU Affinity of a Windows Process Permanently The best way to set a CPU affinity permanently on Windows is to use Process Lasso. The custom CPU affinity will be applied each time the process is run. Download Process Lasso Process
一、什么是cpu亲和性(affinity) CPU的亲和性, 就是进程要在指定的 CPU 上尽量长时间地运行而不被迁移到其他处理器,也称为CPU关联性;再简单的点的描述就将制定的进程或线程绑定到相应的cpu上;在多核运行的机器上,每个CPU本身自己会有缓存,缓存着进程使用的信息,而进程可能会被OS调度到其他CPU上,如此,CPU cache...
