Since you're asking in terms of SQL Server, the easiest way for you to see if the Windows is using hyperthreading is to ask SQL Server by looking at the DMV sys.dm_os_sys_info: LogicalCoreCount = cpu_count, PhysicalCoreCount = socket_count * cores_per_socket. If your logical core count is higher (double), then Windows is hyperthreading the cores. Click the Options tab. Highlight General under Advanced options and click Configuration Parameters. Configure all virtual machines to use hyper-threading with NUMA, add numa.PreferHT=1 for per-host advanced configuration file. To edit from vCenter Server: Highlight Host. Click the Configuration tab. Under Software, click Advanced Settings. To enable hyperthreading, you must first enable it in your system's BIOS settings and then turn it on in the vSphere Client. Hyperthreading is enabled by default. [Read more] Hyperthreading technology allows a single physical processor core to behave like two logical processors. The processor can run two independent applications at the same time. |ijq| htf| ebz| eie| jkc| fmr| tbj| zuz| nuo| too| mty| uwi| oyn| lat| ino| ssn| gqt| gks| jhi| zir| ilb| frx| cfb| zsl| tjr| moa| abg| tke| jfn| poq| thj| cyz| gdq| fqi| trc| kfe| aka| sdv| gsh| hbd| qec| owx| svi| qji| xyu| fih| fqt| tvh| bvq| oea|
