powershell设置虚拟内存

#如果物理内存≤8GB
#虚拟内存最小1.25倍于物理内存
#虚拟内存最大2倍于物理内存

#如果物理内存＞8GB
#虚拟内存最小12GB
#虚拟内存最大16GB

$mem=Get-WmiObject -Class Win32_PhysicalMemory | Measure-Object -Property Capacity -Sum | % {[math]::round(($_.sum / 1GB), 2)}
$MinSize=1000
$MaxSize=12000
if($mem -le 8){
$MinSize=1.25*$mem*1024
$MaxSize=2*$mem*1024
}

if($mem -gt 8){
$MinSize=1.5*8*1024
$MaxSize=2.0*8*1024
}

$MinSize
$MaxSize

cmd.exe /c "wmic computersystem where name='%computername%' set AutomaticManagedPagefile=False"
cmd.exe /c "wmic pagefileset where name='C:\\pagefile.sys' set InitialSize=$MinSize,MaximumSize=$MaxSize"

#设置完后重启生效
