vSMP Consolidate
If it is certain that a workload in a virtual machine benefits from cache-sharing and does not benefit from bigger cache-capacity, such
preference can be specified by enabling vSMP-consolidation, which causes sibling vCPUs from a multi-processor virtual machine to
be scheduled within an LLC. Note that such preference may not always be honored, depending on the availability of pCPUs.
To enable vSMP-consolidate for a virtual machine, take the following steps in vSphere Client:
1. Right click the virtual machine and select Edit Settings.
2. Select the Options tab.
3. Under Advanced, click General, and on the right click the Configuration Parameters button.
4. Click Add Row.
5. Add sched.cpu.vsmpConsolidate set to true.
