Powershell和Stackoverflow新手。这是我的第一个Powershell脚本，我正试图尽我所能优化它。我的目标是让代码尽可能高效地运行。在这方面的任何帮助/建议都将不胜感激！
此脚本显示新的“Established”TCP连接（Get-NetTCPConnection）及其关联的DNS主机名（Resolve-DnsName）。将每个新连接与以前连接的数组进行比较。如果它们具有相同的“*RemoteAddress *”，则DNS主机名将复制到新连接并显示;否则，它将创建一个新的（Resolve-DnsName）（Start-ThreadedJob），并继续移动到下一个新连接。一旦作业为“Completed”，它将复制“NameHost”并显示该连接。
我的理解遇到了一个障碍。当代码运行时，作业“Ids”似乎增加得非常快，即使在上一个作业和新作业之间没有创建新作业。
要测试该脚本，请运行该脚本并访问任意站点。请观察“Id”是否快速增加。请注意，它将在“C：\Temp\Active_Connections.csv”中创建日志文件

$logFile = 'C:\Temp\Active_Connections.csv'
if (-not(Test-Path $logFile -PathType Leaf)){
    New-Item -ItemType File -Force -Path $logFile | Out-Null
    } else {
    Clear-Content $logFile
}
$headersAdded = $true
$newConnections = @()
While ($true){
    $connections = @(Get-NetTCPConnection)
    foreach ($connection in $connections){
        if ($connection.State -eq "Established"){
            if ($newConnections.InstanceID -notcontains $connection.InstanceID){
                if ($newConnections.RemoteAddress -notcontains $connection.RemoteAddress){
                    if ((Get-Job).Name -notcontains $connection.RemoteAddress){
                        Start-ThreadJob -Name $connection.RemoteAddress -ScriptBlock {param($remoteAddress) Resolve-DNSName -Name $remoteAddress} -ArgumentList $connection.RemoteAddress >$null
                    }else{
                        $job = Get-Job | Where-Object {$_.Name -eq $connection.RemoteAddress}
                        if ($job.State -eq "Completed"){
                            Add-Member -InputObject $connection -MemberType NoteProperty -Name "Id" -Value $job.Id -Force
                            Try {
                                $receivedJob = $job | Receive-Job -ErrorAction Stop
                                Add-Member -InputObject $connection -MemberType NoteProperty -Name "NameHost" -Value $receivedJob.NameHost -Force
                            }catch{
                                $na = "N/A"
                                Add-Member -InputObject $connection -MemberType NoteProperty -Name "NameHost" -Value $na -Force
                            }
                            #Remove-Job -Id $job.Id
                        }
                    }
                }else{
                    foreach ($newConnection in $newConnections){
                        if ($newConnection.RemoteAddress -eq $connection.RemoteAddress){
                            Add-Member -InputObject $connection -MemberType NoteProperty -Name "NameHost" -Value $newConnection.NameHost -Force
                        }
                    }
                }
            }
            if ($null -ne $connection.NameHost){
                if ($headersAdded) {
                    $formatting = @{n='CreationTime';e={$_.CreationTime.ToString("h:mm:ss tt")}},'Id','LocalAddress','LocalPort','RemoteAddress','RemotePort','NameHost'
                    $properties = @{Expression="CreationTime";Width=13},@{Expression="Id";Width=4},@{Expression="LocalAddress";Width=15},@{Expression="LocalPort";Width=10;Alignment="Left"},@{Expression="RemoteAddress";Width=15},@{Expression="RemotePort";Width=10;Alignment="Left"},@{Expression="NameHost";Width=100}
                    ($connection | Select-Object $formatting | Format-Table -Property $properties | Out-String).Trim() | Tee-Object -FilePath $logFile -Append
                    $headersAdded = $false
                } else {
                    ($connection | Select-Object $formatting | Format-Table -HideTableHeaders -Property $properties | Out-String).Trim() | Tee-Object -FilePath $logFile -Append
                }
                $newConnections += $connection
            }
        }
    }
}

请，让我知道我可以做得更好，如果你有任何想法，为什么工作ID的增加这么快之间的新连接。
谢谢你的帮助克里斯
