Number Of Processors

Description:

Number of Processors is the number of processor sockets detected on the server. It is only recommended to have up to 2 processors on the server. [3]

An additional note is displayed if Type is set to VMware and greater than 2 processors. [1]

How This Is Checked

([array](Get-WmiObject -Class Win32_Processor)).count

Number Of Logical and Physical Cores

Show the number of Physical and Logical cores presented to the OS. This is provided by the WmiObject class Win32_Processor.

  • We show a warning if we have more than 24 Logical Cores and running Exchange 2013/2016 [2]
  • We show a warning if we have more than 48 Logical Cores and running Exchange 2019 [2]

How This Is Checked

$processor = Get-WmiObject -Class Win32_Processor
$processor |ForEach-Object {$logical += $_.NumberOfLogicalProcessors; $physical += $_.NumberOfCores}
PS C:\> $logical
24
PS C:\> $physical
12

Max Processor Speed

Check to see what the Max Processor Speed is set to for the processor. If the processor is throttled which may be a result of a misconfigured Power Plan.

NOTE: If Power Plan isn't set to High Performance and the processor is being throttled, this will be flagged that Power Plan is the cause and to fix it ASAP.

How This Is Checked

$processor = Get-WmiObject -Class Win32_Processor
$throttled = $processor | Where-Object {$_.CurrentClockSpeed -lt $_.MaxClockSpeed}

if ($throttled) {
    Write-Host ("Throttling your CPU")
}
