Virtual NUMA and Dynamic Memory features cannot be used at the same time. For more info, see Understanding Non-uniform Memory Access. Microsoft SQL Server is an example of NUMA aware application. Only NUMA-aware applications can benefit of vNUMA. Performance penalties due to remote memory access are successfully avoided. Inside a virtual machine, when a workload allocates local memory for data, and accesses that data in the same NUMA node, fast local memory access results on the underlying physical system. There is no distinction between a virtual and a physical NUMA from the workload's perspective. Exposing a virtual NUMA topology into a virtual machine allows the guest operating system and any NUMA-aware applications running within it to take advantage of the NUMA performance optimizations, just as they would when running on a physical computer. By default, this virtual NUMA topology is optimized to match the NUMA topology of the underlying host computer.

In Windows Server 2016, Hyper-V presents a virtual NUMA topology to virtual machines. In such virtual machine configuration, if virtual processors and memory are not allocated from the same NUMA node, workloads may have bad performance due to the inability to take advantage of NUMA optimizations. When creating such large virtual machines, memory from multiple NUMA nodes on the host system will likely be utilized. A single virtual machine can be assigned up to 240 virtual processors and 12 TB of memory. To enable virtualizing large scale-up workloads, Hyper-V in Windows Server 2016 expanded virtual machine scale limits. The following are additional best practices for configuring a client version of Windows in a virtual machine to reduce the overall CPU usage:ĭisable background services such as SuperFetch and Windows Search.ĭisable scheduled tasks such as Scheduled Defrag. Improve server applications to reduce periodic activity (such as timers).Ĭlose Server Manager on both the host and guest operating systems.ĭon't leave Hyper-V Manager running since it constantly refreshes the virtual machine's thumbnail. Review the ETW trace providers that are on by default by running logman.exe query -ets Review the scheduled tasks and services that are enabled by default. Keep the Windows guest operating system on the sign-in screen when it is not being used and disable the screen saver. Remove unused devices such as the CD-ROM and COM port, or disconnect their media. Remove the emulated network adapter through the virtual machine settings dialog box (use the Microsoft Hyper-V-specific adapter). Install the latest version of the Virtual Machine Integration Services. The following are several best practices for minimizing the background CPU usage of a virtual machine: Windows guests typically use less than one percent of one CPU when they are idle. Minimizing the background activity in idle virtual machines releases CPU cycles that can be used elsewhere by other virtual machines. Increase the number of virtual processors if the virtual machine requires more than one CPU of processing under peak load. This is because of the additional overhead that is associated with multiple virtual processors, such as additional synchronization costs in the guest operating system. Virtual machines that have loads that are not CPU intensive should be configured to use one virtual processor. Hyper-V in Windows Server 2016 supports a maximum of 240 virtual processors per virtual machine. For a list of supported guest operating systems, see Hyper-V Overview. This is the first step in tuning performance in a server running Hyper-V. The services decrease the CPU usage of the guests, from idle guests to heavily used guests, and improves the I/O throughput.

The Virtual Machine Integration Services include enlightened drivers for the Hyper-V-specific I/O devices, which significantly reduces CPU overhead for I/O compared to emulated devices. In this article Virtual machine integration services
