如何模拟cpu和内存压力powershell

# 模拟CPU压力
function SimulateCPULoad {
    $cpuCores = (Get-WmiObject -Class Win32_Processor).NumberOfCores
    $loadPercentage = 80  # 设置CPU负载百分比

    $processes = @()
    for ($i = 0; $i -lt $cpuCores; $i++) {
        $process = Start-Process -FilePath "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -ArgumentList "-Command while (1) { }" -PassThru
        $processes += $process
    }

    Start-Sleep -Seconds 10  # 运行10秒钟

    foreach ($process in $processes) {
        Stop-Process -Id $process.Id
    }
}

# 模拟内存压力
function SimulateMemoryLoad {
    $memorySize = (Get-WmiObject -Class Win32_ComputerSystem).TotalPhysicalMemory
    $loadPercentage = 80  # 设置内存负载百分比

    $memoryLoad = $memorySize * $loadPercentage / 100
    $memoryLoad = [math]::Floor($memoryLoad / 1024 / 1024)  # 转换为MB

    $buffer = New-Object Byte[] $memoryLoad
    while ($true) {
        $buffer += New-Object Byte[] 1024
    }
}

# 调用函数进行模拟压力测试
