The processor performance can be a bottleneck if there is not enough main memory for the CPU. In general, before optimizing, you should use performance monitoring to measure exactly where the server performance bottlenecks originated and if they are attributable to the processor or memory ( Figure 1). SLAT allows the hypervisor to accelerate memory access. The function can be read out with systeminfo.exe and is shown as Second Level Address Translation The function is integrated into Intel processors in the form of Extended Page Tables (EPT) and into AMD processors as Nested Page Tables (NPT). If you are using Hyper-V, the processor must be able to handle Second Level Address Translation (SLAT).
Even if obsolete server hardware can be pimped with new processors, line bottlenecks still can occur quickly if the rest of the server's hardware does not match the new processor's performance. The RAM performance and size, as well as the storage media's I/O performance, must match the processor. In this case, a higher clock speed is infinitely preferable to having more cores that are not used at all by the VM in question. Therefore, more cores are not always significantly faster than fewer cores.Ībove all, Hyper-V performance benefits from clock speed, because the hypervisor distributes a server's resources to the virtual machines (VMs), which can share a core. The cores should run at the highest possible frequency, because a processor with fewer cores but twice the clock speed can be significantly faster than a processor with several cores and a normal clock speed. Ideally, you should use the most up to date Server 2016 hardware possible (e.g., 64-bit processors). The performance of Windows Server 2016 depends on the underlying hardware. In this article, I will be optimizing the RAM, CPU, cache, and storage media. Depending on its purpose, the server requires different tweaks to unleash its true performance. Windows Server 2016's default settings might not always meet your network requirements.
