使用SMO从SQL Server收集数据非常慢

我得到了这个Powershell脚本，它获取有关SQL Server是否安装在主机上并获取SQL Server版本和其他详细信息的信息。使用SMO从SQL Server收集数据非常慢

它从txt文件获取主机列表并将信息保存到DataTable。

$data = New-Object ('System.Data.DataTable') 
$data.Columns.Add('Host name') | Out-Null 
$data.Columns.Add('Ip Address') | Out-Null 
$data.Columns.Add('SQL Server Product Name') | Out-Null 
$data.Columns.Add('SQL Server Edition') | Out-Null 
$data.Columns.Add('SQL Server Version') | Out-Null 
$data.Columns.Add('SQL Server Type') | Out-Null 
$data.Columns.Add('SQL Server Status') | Out-Null 

Get-Content .\servers.txt | ForEach { 
    [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') | out-null 
    $row = $data.NewRow() 
    $row['Host name'] = $_ 
    try { 
     $row['Ip Address'] = [Net.Dns]::GetHostEntry($_).AddressList.IpAddressToString 
    } 
    catch [System.Net.Sockets.SocketException] { 
     $row['Ip Address'] = 'Offline' 
    } 

    If ($row['Ip Address'] -eq 'Offline') { 
     $row['SQL Server Product Name'] = 'N/A' 
     $row['SQL Server Edition'] = 'N/A' 
     $row['SQL Server Version'] = 'N/A' 
     $row['SQL Server Type'] = 'N/A' 
     $row['SQL Server Status'] = 'N/A' 
    } 
    else { 
     $smo = New-Object ('Microsoft.SqlServer.Management.Smo.Server') $_ 
     $row['SQL Server Product Name'] = $smo.Product + ' ' + $smo.ProductLevel 
     $row['SQL Server Edition'] = $smo.Edition 
     $row['SQL Server Version'] = $smo.VersionString 
     $row['SQL Server Type'] = $smo.ServerType 
     $row['SQL Server Status'] = $smo.Status 
    } 
    $smo.ConnectionContext.Disconnect() 
    $data.Rows.Add($row) 
} 

$data | Format-Table -AutoSize

此脚本的问题是运行需要很长时间（超过一小时的113个服务器列表）。

有什么方法可以加快进程？

您可以使用后台作业异步运行脚本（您将不得不使用3个cmdlet：start-job,get-job和receive-job）。

从About_remote_jobs

引
启动远程JOB返回到本地计算机的结果（ASJOB）

To start a background job on a remote computer that returns the command 
results to the local computer, use the AsJob parameter of a cmdlet such 
as the Invoke-Command cmdlet. 

When you use the AsJob parameter, the job object is actually created on 
the local computer even though the job runs on the remote computer. When 
the job is completed, the results are returned to the local computer. 

You can use the cmdlets that contain the Job noun (the Job cmdlets) to 
manage any job created by any cmdlet. Many of the cmdlets that have 
AsJob parameters do not use Windows PowerShell remoting, so 
you can use them even on computers that are not configured for 
remoting and that do not meet the requirements for remoting.
