More CPU power

[Lerager]

Hi'

I would like to know if i can get more CPU resources on my VM, and how.

Be kind i not a hardware geek

This is my Host:

And my vm is a workstation 12Pro running win 7 x64

As you can see Number of cpu and core is set to 1 / 1

Cpu can be set 1,2,48,16

Core per cpu to 1,2,3,4  6,8,12,16

How to optimal change this to get more power.

And can I do that ion the fly ect. when i working in a heavy Graph program.

Thank You

Your CPU is 4 core/8 thread Kaby Lake generation CPU.

The most you can go with is 6 virtual CPUs to leave some cores for the host (e.g. 1 processor, 6 cores = 6 virtual CPUs; or 2 processors with 2 cores = 4 virtual CPUs). I would avoid assigning total virtual CPUs that is odd in number (1 being the exception). You can keep the number of virtual processors to 1 as the host only has one CPU. Assuming you have Windows 7 Professional or Enterprise, it should be able to recognise 2 virtual sockets but there is no inherent advantage to do so inside a VM as the host machine is only a single CPU socket machine.

Getting optimal use of the host CPU is also dependent on the guest OS. As the guest OS is Windows 7 (released in 2010), it cannot take advantage of instruction sets that are present in newer CPUs. For example, to mitigate against performance hit in I/O intensive workloads due to the Meltdown patch, the INVPCID instruction (available in Haswell and newer CPUs, i.e. 2013 and onwards) is used. But Windows 7 cannot make use of it; so the Windows 7 VM will suffer a performance penalty as a result.

Thank's

That's better. I change to 1 Cpu 4 Core
