Problem in Identifying L1 cache in Virtaul Machine

Question

_{Thursday, November 29, 2018 5:34 AM}

Hi,

I am installing a Virtual Machine on the physical host having(8vCPU) and installing windows server 2012R2 OS.

But as I check under Task Manager>Performance, the L1 cache is showing N/A.

How I will be able to know the what amount of L1 cache memory my Virtual Machine is using?

Kindly help!!

Hi

Thanks for your question.

By design, L1 Cache doesn’t exist in the VM system, as shown N/A in the performance of the task manager.

Meanwhile, we could use the cmdlets wmic to check the current cache size, even more detailed information about CPU on the system. Please refer to the following article,

https://www.techvigil.com/tips-tricks/379/verify-processor-cache-size-speed/

wmic cpu get L2CacheSize, L2CacheSpeed, L3CacheSize, L3CacheSpeed

wmic cpu list full

wmic cpu get >cpuinfo.txt

Please Note: Since the web site is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information.

Besides, I find the symptom in my lab, when the VM is Hyper host, we can see L1 Cache shown in the task manager of this VM as below. You could test it. If any concern, please feel free to let me know.

Best regards,

Michael
